<br />
:Probably. (My script to generate these is not perfect yet, as you can see.) Might be easiest to just add some extra in-between frames in your favorite image editor to show that the grid's moving along with the ship. I may do that later if I have the time.

[[Image:Gosperglidergun.gif|framed|right|The first known gun, the [[Gosper glider gun]]]]<br />
A '''gun''' is a stationary pattern that repeatedly emits [[spaceship]]s (or [[rake]]s) forever. By far the most common type of guns are '''glider guns''', which emit [[glider]]s (the most well-known of which is the [[Gosper glider gun]]); however, guns that emit spaceships of other speeds, including [[c/2 orthogonal]], [[2c/5 orthogonal]], and [[c/12 diagonal]], have also been created.<br />
<br />
==History==<br />
The first gun to be discovered, the [[Gosper glider gun]], was found by [[Bill Gosper]] in [[:Category:patterns found in 1970|1970]], being the first known pattern in [[Conway's Game of Life]] to exhibit [[infinite growth]]. Since then, many guns have been constructed with various periods and that fire spaceships of various speeds. Due to simple [[glider synthesis|glider syntheses]] of the [[Types_of_spaceships#Standard_spaceship|standard spaceships]] many c/2 spaceship guns are known. The first gun that did not fire gliders or c/2 spaceships was a '''Cordergun''' (a gun that fires [[Cordership]]s) constructed by [[Jason Summers]] in July, [[:Category:patterns found in 1999|1999]]<ref>{{cite web|url=http://entropymine.com/jason/life/status.html |title=Game of Life Status page |accessdate=October 15, 2010}}</ref> based on a synthesis of a variation of the [[7-engine Cordership]] by [[Stephen Silver]]. In March, [[:Category:patterns found in 2003|2003]] [[Noam Elkies]] completed the synthesis of [[60P5H2V0]] which [[Dave Greene]] used to construct the [[P416_60P5H2V0_gun|first 2c/5 spaceship gun]] in April of the same year.<br />
<br />
In July, [[:Category:patterns found in 2010|2010]] Dave Greene constructed a few guns for a [[gemini|geminoid]] spaceship.<ref>{{Cite web|url=http://pentadecathlon.com/lifeNews/2010/07/gemini_guns_1.html|title=Gemini guns|author=Adam P. Goucher|date=July 30, 2010|accessdate=October 15, 2010}}</ref> These are the first guns that shoot obliquely-traveling spaceships and are, in terms of their bounding boxes, the largest patterns constructed in Life.<br />
<br />
On February 17, [[:Category:patterns found in 2013|2013]] [[Josh Ball]] discovered a simple [[c/7 orthogonal]] spaceship, [[loafer]]. Adam P. Goucher found a synthesis for loafer later that day, allowing the construction of c/7 orthogonal spaceship guns.<br />
<br />
==Barrels==<br />
It is not uncommon for glider guns to have multiple '''barrels'''; that is, streams of gliders that come out along multiple different paths. For example, the [[B-52 bomber]] is said to be double-barreled because it produces two streams of gliders (one toward the northwest and another toward the southeast). [[Gunstar]] and its variants all have four barrels, and [[P94S]] contains a whopping 12 barrels. Given a gun with multiple barrels, one can eliminate barrels by simply placing an [[eater 1]] in the path of the unwanted glider streams.<br />
<br />
==Pseudo-period guns==<br />
A '''pseudo-[[period]] gun''' (as opposed to a [[#True-period guns|true-period gun]]) is a gun that emits a period n stream of spaceships (or rakes) via a mechanism that oscillates with a period different from n -- this period will necessarily be a multiple of n. Pseudo period n glider guns are known to exist for all periods greater than or equal to 14, with smaller periods being impossible. The first pseudo period 14 gun was built by [[Dietrich Leithner]] in [[:Category:Patterns found in 1995|1995]].<br />
<br />
==True-period guns==<br />
A '''true-period gun''' (as opposed to a [[#Pseudo-period guns|pseudo-period gun]]) is a gun that emits a period n stream of spaceships (or rakes) via a mechanism that oscillates with period equal to n. True period n guns are known to exist for all periods greater than 61<ref>{{Cite web|url=http://www.radicaleye.com/lifepage/patterns/bhept/bhept.html|title=My Experience with B-heptominos in Oscillators|author=Dave Buckingham|accessdate=May 14, 2009|date=October 12, 1996)}}</ref>, but only a few smaller periods have been achieved, namely [[Period-20 glider gun|20]], [[True_period_22_gun|22]], [[True_period_24_gun|24]], [[Gosper_glider_gun|30]], [[Period-36_Glider_Gun|36]], [[Period-40 glider gun|40]], [[P44_pi-heptomino_hassler|44]], [[Period-45_glider_gun|45]], [[New gun 1|46]], [[True_period_24_gun|48]], [[Period-50 glider gun|50]], 54, 55, 56, 57, 58, [[Period-59_glider_gun|59]], [[Period-60_glider_gun|60]] and [[Period-61_glider_gun|61]]. Credits for these small period guns are as follows: p30, p46 and p60 by [[Bill Gosper]] in [[:Category:patterns found in 1970|1970]]-[[:Category:patterns found in 1971|1971]], p44 by [[David Buckingham]] in [[:Category:patterns found in 1992|1992]], p50 by [[Dean Hickerson]] in [[:Category:patterns found in 1996|1996]], p24 and p48 by [[Noam Elkies]] in [[:Category:patterns found in 1997|1997]], p54 and p56 by [[Dietrich Leithner]] in early [[:Category:patterns found in 1998|1998]], p55 by [[Stephen Silver]] in late 1998, p22 by [[David Eppstein]] in [[:Category:patterns found in 2000|2000]], p36 by [[Jason Summers]] in [[:Category:patterns found in 2004|2004]], p59 by [[Adam P.

==Guns in Life-like cellular automata==<br />
Due to the existence of some small spaceships in [[Cellular_automaton#Life-like_cellular_automata|Life-like cellular automata]] with birth at two live neighbours (B2), many low-period spaceship guns have been found using tools such as [[WinLifeSearch]]. In contrast, there are very few rules without B2 that are known to contain guns. The following is a list of rules without B2 that have known guns:<br />

The first pseudo period 14 gun was built by [[Dietrich Leithner]] in [[:Category:Patterns found in 1995|1995]].<br />

==Guns in Life-like cellular automata==<br />
Due to the existence of some small spaceships in [[Cellular_automaton#Life-like_cellular_automata|Life-like cellular automata]] with birth at two live neighbours (B2), many low-period spaceship guns have been found using tools such as [[WinLifeSearch]]. In contrast, there are very few rules without B2 that are known to contain guns. The following is a list of rules without B2 that have known guns:<br />

[[Image:lwss.gif|framed|right|The lightweight spaceship in [[Conway's Game of Life]]]]A '''spaceship''' (much less commonly referred to as a '''glider'''<ref>{{cite web|url=http://www.argentum.freeserve.co.uk/lex_g.htm#glider |title=Glider |work=The Life Lexicon |publisher=Stephen Silver |accessdate=April 18, 2009}}</ref> or a '''fish'''<ref>{{cite web|url=http://www.argentum.freeserve.co.uk/lex_f.htm#fish |title=Fish |work=The Life Lexicon |publisher=Stephen Silver |accessdate=April 18, 2009}}</ref>) is a finite [[pattern]] that returns to its initial state after a number of [[generation]]s (known as its [[Period#Spaceships|period]]) but in a different location.<br />
<br />
<br />
__TOC__<br />
<br />
==Spaceship Speed==<br />
{{main|Speed}}<br />
The speed of a spaceship is the number of [[cell]]s that the pattern moves during its period divided by the period length. This is expressed in terms of ''c'' (the metaphorical "speed of light") which is one cell per generation; thus, a spaceship with a period of five that moves two cells to the left during its period travels at the speed of [[2c/5 orthogonal|2c/5]]. Until the construction of [[Gemini]] in May [[:Category:patterns found in 2010|2010]], all known spaceships in [[Conway's Game of Life|Life]] traveled either orthogonally (only horizontal or vertical displacement) or diagonally (equal horizontal and vertical displacement). Other recently constructed large spaceships such as the [[waterbear]] and the [[Parallel HBK]]. It is known that Life has spaceships that travel in all rational directions at arbitrarily slow speeds (see [[universal constructor]]). Spaceships traveling in other directions and at different speeds have also been constructed in other two dimensional [[cellular automaton|cellular automata]].<ref>{{cite web|url=http://fano.ics.uci.edu/ca/ |title=Gliders in Life-Like Cellular Automata |publisher=David Eppstein|accessdate=April 18, 2009}}</ref><br />

==Spaceship types==<br />
<br />
[[Image:AlmostKnightship.png|framed|right|An "almost knightship"<br />]]<br />
{{main|Types of spaceships|Spaceship types}}<br />
Although Spaceships are most commonly categorized by their speed and direction, other categorizations have been applied to spaceships based on their appearances, components, or other properties. One such categorization is the symmetry of spaceships: spaceships can be bilaterally symmetric, Such as Tim Coe's snail, may exhibit [[Types_of_spaceships#Glide_symmetric_spaceship|glide symmetry]], such as the glider, or may be asymmetric, such as the caterpillar. Other, somewhat subjective categorizations have also been made, such as [[greyship]]s, spaceships filled with large amounts of static, live cells, or [[Types_of_spaceships#Smoking_ship|smoking ships]], which produce large [[spark]]s, a notable example being the [[Schick engine]]. A spaceship may also support other components which would not function as spaceships on their own. Given a freestanding spaceship, such additional components are often referred to as [[tagalong]]s; perhaps even pushalongs. Unstable spaceships immersed in a sustaining cloud are known as [[Types_of_spaceships#Flotilla|flotillae]]. A well known example is that of the [[overweight spaceship]]s, which are unstable alone but may be 'escorted' by two or more smaller spaceships. <br />

==History==<br />
<br />
The four smallest spaceships in life, the [[glider]], [[lightweight spaceship]], [[middleweight spaceship]] and [[heavyweight spaceship]], were all found by hand in [[:Category:patterns found in 1970|1970]]. For almost twenty years spaceship development was limited to adding [[Tagalong|tagalongs]] to the known [[c/2 orthogonal|c/2]] spaceships. Significant advances in spaceship technology came in [[:Category:patterns found in 1989|1989]], when [[Dean Hickerson]] began using [[Computer search|automated searches]] based on a depth-first backtracking algorithm. These searches found orthogonal spaceships with speeds of [[c/3 orthogonal|c/3]], [[c/4 orthogonal|c/4]], and [[2c/5 orthogonal|2c/5]], as well as the first spaceship other than the glider to travel at the speed of [[c/4 diagonal|c/4]] diagonally, dubbed the [[big glider]]. Hickerson also found several ways to combine [[switch engine]]s to create the first diagonal [[c/12 diagonal|c/12]] spaceships, named [[Cordership]]s in honour of [[Charles Corderman]]. The next spaceship speed to be discovered was that of the orthogonal [[c/5 orthogonal|c/5]] [[snail]], found by [[Tim Coe]] in [[:Category:patterns found in 1996|1996]], with a program he had designed using breadth-first searching, and which could split tasks between multiple CPUs.<ref>{{cite web|url=http://www.radicaleye.com/lifepage/patterns/p5ss.html |title=c/5 Orthogonal spaceship |author=Tim Coe |publisher=Paul's Page of Conway's Life Miscellany |accessdate=April 18, 2009}}</ref> In the following year [[David Bell]] found the much smaller c/5 [[spider]] using [[lifesrc]], a program based on Hickerson's search algorithm.<ref>{{cite web|url=http://radicaleye.com/lifepage/patterns/newc5/newc5.html |title=New c/5 spaceship |author=David Bell |publisher=Paul's Page of Conway's Life Miscellany |accessdate=April 18, 2009}}</ref><br />
<br />
In March of [[:Category:patterns found in 1998|1998]] [[David Eppstein]] created [[gfind]], a breadth-first program that uses a depth-first search to limit the size of the search queue.<ref>{{cite web|url=http://arxiv.org/PS_cache/cs/pdf/0004/0004003v2.pdf |title=Searching for Spaceships (PDF) |author=David Eppstein |accessdate=April 18, 2009}}</ref> In [[:Category:patterns found in 2000|2000]] he used this program to find the first spaceship that travels at the speed of [[2c/7 orthogonal]]ly, the [[weekender]]. A search by [[Paul Tooke]] using the same program found the first [[c/6 orthogonal]] spaceship, the [[dragon]], later that year. Also in 2000, [[Jason Summers]] found the first [[c/5 diagonal]] spaceship using David Bell's lifesrc program.<br />
<br />
In [[:Category:patterns found in 2004|2004]] [[Gabriel Nivasch]], with the help of Jason Summers and David Bell, finished construction on the [[caterpillar]], the first known orthogonal [[17c/45 orthogonal|17c/45]] spaceship, which made use of the [[17c/45 reaction]].<br />
<br />
In May [[:Category:patterns found in 2010|2010]] [[Andrew J. Wade]] created a universal constructor-based spaceship, [[Gemini]], which travels at a speed of (5120,1024)c/33699586.<ref>{{cite web|url=http://pentadecathlon.com/lifeNews/2010/05/oblique_life_spaceship_created.html|title=Oblique Life spaceship created|date=May 19, 2010|work=Game of Life News|author=Adam P. Goucher|accessdate=May 21, 2010}}</ref> This was the first explicitly constructed spaceship in Life to travel in an [[Types_of_spaceships#Knightship|oblique]] direction, and also yielded the first explicit method of constructing arbitrarily slow spaceships.<br />
<br />
In Febuary 2013, the first c/7 orthogonal spaceship, loafer, was discovered by Josh Ball.<br />
<br />
In July 2014 several [[half-baked knightship|half-bakery-based knightships]] were constructed using a new technique that did not require universal-constructor circuitry. These produced spaceships that were both much slower and much smaller than the Gemini variants.<br />
<br />
In September 2014, Dave Greene and Chris Cain completed two [[31c/240 orthogonal]] spaceships, along the same general lines as the original Caterpillar but using a number of new mechanisms.<br />
<br />
In December 2014, an oblique caterpillar dubbed the [[Waterbear]] was completed by Brett Berger, traveling at (23,5)c/79.<br />
<br />
In December 2015, Chris Cain completed a diagonal self-constructing spaceship -- a [[Demonoid|"0hd Demonoid"]] -- based on Geminoid technology, adapted from a larger 10hd version constructed in November in collaboration with [[Dave Greene]].<br />

[[Image:Gosperglidergun.gif|framed|right|The first known gun, the [[Gosper glider gun]]]]<br />
A '''gun''' is a stationary pattern that repeatedly emits [[spaceship]]s (or [[rake]]s) forever. By far the most common type of guns are '''glider guns''', which emit [[glider]]s (the most well-known of which is the [[Gosper glider gun]]); however, guns that emit spaceships of other speeds, including [[c/2 orthogonal]], [[2c/5 orthogonal]], and [[c/12 diagonal]], have also been created.<br />
<br />
==History==<br />
The first gun to be discovered, the [[Gosper glider gun]], was found by [[Bill Gosper]] in [[:Category:patterns found in 1970|1970]], being the first known pattern in [[Conway's Game of Life]] to exhibit [[infinite growth]]. Since then, many guns have been constructed with various periods and that fire spaceships of various speeds. Due to simple [[glider synthesis|glider syntheses]] of the [[Types_of_spaceships#Standard_spaceship|standard spaceships]] many c/2 spaceship guns are known. The first gun that did not fire gliders or c/2 spaceships was a '''Cordergun''' (a gun that fires [[Cordership]]s) constructed by [[Jason Summers]] in July, [[:Category:patterns found in 1999|1999]]<ref>{{cite web|url=http://entropymine.com/jason/life/status.html |title=Game of Life Status page |accessdate=October 15, 2010}}</ref> based on a synthesis of a variation of the [[7-engine Cordership]] by [[Stephen Silver]]. In March, [[:Category:patterns found in 2003|2003]] [[Noam Elkies]] completed the synthesis of [[60P5H2V0]] which [[Dave Greene]] used to construct the [[P416_60P5H2V0_gun|first 2c/5 spaceship gun]] in April of the same year.<br />
<br />
In July, [[:Category:patterns found in 2010|2010]] Dave Greene constructed a few guns for a [[gemini|geminoid]] spaceship.<ref>{{Cite web|url=http://pentadecathlon.com/lifeNews/2010/07/gemini_guns_1.html|title=Gemini guns|author=Adam P. Goucher|date=July 30, 2010|accessdate=October 15, 2010}}</ref> These are the first guns that shoot obliquely-traveling spaceships and are, in terms of their bounding boxes, the largest patterns constructed in Life.<br />
<br />
On February 17, [[:Category:patterns found in 2013|2013]] [[Josh Ball]] discovered a simple [[c/7 orthogonal]] spaceship, [[loafer]]. Adam P. Goucher found a synthesis for loafer later that day, allowing the construction of c/7 orthogonal spaceship guns.<br />
<br />
==Barrels==<br />
It is not uncommon for glider guns to have multiple '''barrels'''; that is, streams of gliders that come out along multiple different paths. For example, the [[B-52 bomber]] is said to be double-barreled because it produces two streams of gliders (one toward the northwest and another toward the southeast). [[Gunstar]] and its variants all have four barrels, and [[P94S]] contains a whopping 12 barrels. Given a gun with multiple barrels, one can eliminate barrels by simply placing an [[eater 1]] in the path of the unwanted glider streams.<br />
<br />
==Pseudo-period guns==<br />
A '''pseudo-[[period]] gun''' (as opposed to a [[#True-period guns|true-period gun]]) is a gun that emits a period n stream of spaceships (or rakes) via a mechanism that oscillates with a period different from n -- this period will necessarily be a multiple of n. Pseudo period n glider guns are known to exist for all periods greater than or equal to 14, with smaller periods being impossible. The first pseudo period 14 gun was built by [[Dietrich Leithner]] in [[:Category:Patterns found in 1995|1995]].<br />
<br />
==True-period guns==<br />
A '''true-period gun''' (as opposed to a [[#Pseudo-period guns|pseudo-period gun]]) is a gun that emits a period n stream of spaceships (or rakes) via a mechanism that oscillates with period equal to n. True period n guns are known to exist for all periods greater than 61<ref>{{Cite web|url=http://www.radicaleye.com/lifepage/patterns/bhept/bhept.html|title=My Experience with B-heptominos in Oscillators|author=Dave Buckingham|accessdate=May 14, 2009|date=October 12, 1996)}}</ref>, but only a few smaller periods have been achieved, namely [[Period-20 glider gun|20]], [[True_period_22_gun|22]], [[True_period_24_gun|24]], [[Gosper_glider_gun|30]], [[Period-36_Glider_Gun|36]], [[Period-40 glider gun|40]], [[P44_pi-heptomino_hassler|44]], [[Period-45_glider_gun|45]], [[New gun 1|46]], [[True_period_24_gun|48]], [[Period-50 glider gun|50]], 54, 55, 56, [[Period-59_glider_gun|59]] and [[Period-60_glider_gun|60]]. Credits for these small period guns are as follows: p30, p46 and p60 by [[Bill Gosper]] in [[:Category:patterns found in 1970|1970]]-[[:Category:patterns found in 1971|1971]], p44 by [[David Buckingham]] in [[:Category:patterns found in 1992|1992]], p50 by [[Dean Hickerson]] in [[:Category:patterns found in 1996|1996]], p24 and p48 by [[Noam Elkies]] in [[:Category:patterns found in 1997|1997]], p54 and p56 by [[Dietrich Leithner]] in early [[:Category:patterns found in 1998|1998]], p55 by [[Stephen Silver]] in late 1998, p22 by [[David Eppstein]] in [[:Category:patterns found in 2000|2000]], p36 by [[Jason Summers]] in [[:Category:patterns found in 2004|2004]], p59 by [[Adam P. Goucher]] in [[:Category:patterns found in 2009|2009]], p45 by [[Matthias Merzenich]] in [[:Category:patterns found in 2010|2010]], p40 by Adam P. Goucher and Matthias Merzenich in March [[:Category:patterns found in 2013|2013]], and p20 by Matthias Merzenich and Noam Elkies in May 2013.<br />
<br />
==Guns in Life-like cellular automata==<br />
Due to the existence of some small spaceships in [[Cellular_automaton#Life-like_cellular_automata|Life-like cellular automata]] with birth at two live neighbours (B2), many low-period spaceship guns have been found using tools such as [[WinLifeSearch]]. In contrast, there are very few rules without B2 that are known to contain guns. The following is a list of rules without B2 that have known guns:<br />

An '''oscillator''' is a [[pattern]] that is a [[predecessor]] of itself. That is, it is a pattern that repeats itself after a fixed number of [[generation]]s (known as its [[period]]). The term is usually restricted to finite patterns that are not [[still life]]s, though still lifes may be thought of as oscillators with period 1. An oscillator is divided into a [[rotor]] and a [[stator]].<br />
<br />
[[cellular automaton|Cellular automaton]] theory recognizes shift periodicity, which refers to a configuration reappearing in shifted form after a lapse of one or more generations. Without the shift, it is an oscillator, but if it moves it would be called a [[glider]] or [[spaceship]]. Strictly speaking "glider" means the little figure so prevalent in [[Conway's Game of Life]], but the more general usage has now become popular. <br />
==Important oscillators by period==<br />
A list of the first-discovered oscillator of each period, as well the current smallest-known oscillator of that period, is provided here. Note that only non-trivial oscillators are considered here, in the sense that there must be at least one [[cell]] that oscillates at the full period. In some cases, it is not known for certain what the first-discovered oscillator of a given period is, and in such situations all possible candidates are listed. For any period 61 or greater an oscillator can be constructed using the Herschel track method. In April, [[:Category:patterns found in 2013|2013]] [[Mike Playle]] found a small 90-degree [[stable reflector]] that allows oscillators of all periods 43 or greater to be constructed.<br />

The '''R-pentomino''' is a [[methuselah]] that was found by [[:Category:Patterns found by John Conway|John Conway]] in [[:Category:Patterns found in 1970|1970]].<ref>{{cite conference|author=Gardner, M.|title=The Game of Life, Part III|booktitle=Wheels, Life and Other Mathematical Amusements|year=1983|publisher=W.H. Freeman|pages=219, 223}}</ref> It is by far the most active [[polyomino]] with fewer than six [[cell]]s; all of the others stabilize in at most 10 [[generation]]s, but the R-pentomino does not do so until generation 1103, by which time it has a population of 116. The [[glider]] it releases in [[generation]] 69, noticed by [[Richard K. Guy]], was the [[First natural glider|first glider ever observed]].<br />
<br />
==Predecessors==<br />
The R-pentomino has several different small predecessors which are of note because they naturally have a longer lifespan. There are three 5-cell [[grandparent]]s of the R-pentomino (which each have a lifespan of 1105 generations) and three 6-cell [[predecessor]]s that evolve into the R-pentomino after 5 generations (and thus have a total lifespan of 1108).<br />
<br />

|[[Image:rpentomino5cell.png|framed|The three 5-cell grandparents of the R-pentomino.]]<br />
|[[Image:rpentomino6cell.png|framed|Three 6-cell predecessors that each evolve into the R-pentomino at generation 5.]]<br />
|}<br />
<br />
==Evolution==<br />
The R-pentomino initially grows in all directions. A [[c/2]] forward growth mechanism emerges at generation 7, and by generation 27 finally separates. From here on this part of the pattern proceeds along the B-heptomino evolution.<br />
<br />
The left-behind chaos is whittled down by generation 40 into two halves, one of which would produce a [[traffic light]] and the other a [[honey farm]], if left on their own. These however react with each other to produce a large cloud of further growth, and by generation 104 this consumes the block left behind by the B-heptomino. The third glider also escapes around this time, followed by a fourth at generation 156.<br />
<br />
The Herschel from the initial B finishes by generation 176, having created a [[ship]], two [[block]]s and two [[glider]]s as usual. By generation 198, a small active intrusion close to these creates two [[beehive]]s (one of which will be later destroyed) and the fifth escaping glider.<br />
<br />
The next surviving objects to be created are a [[boat]] formed at generation 599, a block formed at generation 646 and a glider released at generation 699 (though several temporary blocks, blinkers, boats, beehives, traffic lights and two temporary gliders have been seen by this point).<br />
<br />
A [[toad]] forms at generation 737 and a [[beacon]] at generation 744, but both are destroyed by the activity at generations 751 and 754 respectively.<br />
<br />
The [[pi heptomino]] sequence pops in for a cameo at several points, the longest-surviving instance running between generations 784 and 803. The [[century]] sequence also makes a brief appearence, between generations 316 and 333.<br />
<br />
The stable pattern that results from the R-pentomino has 116 cells and consists of eight blocks, six gliders, four beehives, four [[blinker]]s, one boat, one [[loaf]], and one ship.<br />

'''Eater 1''' (or '''fishhook'''<ref>{{cite web|url=http://www.conwaylife.com/wiki/index.php?title=Lifeline_Volume_2 |title=Lifeline Volume 2 |author=Robert Wainwright |date=June 1971}}</ref> or simply '''eater''') was the first discovered [[eater]]. It was observed independently by several [[Conway's Game of Life|Life]] enthusiasts in [[:Category:Patterns found in 1971|1971]] as the smallest asymmetric [[still life]]. The name "fishhook", which is still occasionally used, was suggested by Clement A. Lessner III and William P. Webb.<br />
<br />
Its ability to eat various objects was discovered by [[Bill Gosper]] late in [[:Category:Patterns found in 1971|1971]]. It is the thirteenth most common still life, being less common than [[mango]] but more common than [[long barge]].<ref>{{cite web|url=http://wwwhomes.uni-bielefeld.de/achim/freq_top_life.html |title=Most seen natural occurring ash objects in Game of Life |author=Achim Flammenkamp |date=September 7, 2004 |accessdate=January 15, 2009}}</ref><br />
<br />
It only takes four [[generation]]s to recover from being hit by a [[glider]], making it the fastest-recovering glider eater, and it is also the smallest glider eater. As such, it appears as a stabilizer at the corner of dozens of [[oscillator]]s including [[36P22]], [[buckaroo]], [[P54 shuttle]], [[pentoad]], [[pre-pulsar shuttle 47]], and [[snacker]].<br />
<br />
==Eating reactions==<br />
Eater 1 is extremely useful as an eater because in addition to being able to eat [[glider]]s, it can also eat [[blinker]]s, [[lightweight spaceship]]s, [[loaf|loaves]], [[middleweight spaceship]]s, [[pre-beehive]]s, [[R-bee]]s and many other patterns, as shown below. Its tail can be used as a [[rock]] that eats an unnamed 7-[[cell]] [[polyplet]]. Its pre-beehive eating reaction is used in the [[period]] [[:Category:Oscillators with period 12|12]] oscillator [[dinner table]].<br />

'''Caterer''' is a [[period]] [[:Category:Oscillators with period 3|3]] [[oscillator]] found by [[:Category:Patterns found by Dean Hickerson|Dean Hickerson]] on August 4, [[:Category:Patterns found in 1989|1989]].<ref>{{CiteHickersonOscillators}}</ref> Its rotor is similar to that of [[jam]]. In terms of its minimum population of [[:Category:patterns with 12 cells|12]] this is the smallest period 3 oscillator, and tied with [[fox]] as the smallest wholly asymmetric oscillator.<!--Mold has glide-reflectivity, NB.--> It is about the forty-second most [[common]] naturally-occurring oscillator, being about as frequent as [[griddle and beehive]].<ref>{{CiteAchim|accessdate=January 15, 2009}}</ref> The [[:Category:Patterns_that_can_be_constructed_with_11_gliders|11]]-glider [[glider synthesis|synthesis]] of the caterer was discovered by [[Tim Coe]].<ref>{{cite web|url=http://home.interserv.com/~mniemiec/lifecred.htm#coe |publisher=Mark D. Niemiec |title=Life Credits |accessdate=June 10, 2011}}</ref><br />
<br />
More generally, any oscillator which serves up a [[bit]] in the same manner, such as [[T-nosed p4]] and [[T-nosed p6]], may be referred to as a caterer.<br />

<div>Just throwing this out there in case anyone has a problem with this.<br />
<br />
My plan is to remove this category from all the pages currently in this category.<br />
<br />
My reasoning is that the vast majority of patterns on this wiki are asymmetric and are notable for reasons other than their lack of symmetry. So this category doesn't serve as anything more than clutter. [[User:FractalFusion|FractalFusion]] ([[User talk:FractalFusion|talk]]) 18:54, 9 April 2016 (UTC)</div>FractalFusion
