==Predecessors==
Like all patterns in [[Conway's Game of Life]] (except for [[Gardens of Eden]]), the U-turner has many predecessors. obviously, not all of them can be listed, so here are some of the more useful or notable ones.
===Still life+methuselah reactions that make U-turners===
Reactions are grouped by the still life involved

===Other predecessors===
The U-turner has one six-cell predecessor:
{{EmbedViewer
|pname = uturnerpredecessor
|position = center
|viewerconfig = #C [[ GPS 10 THUMBSIZE 2 ]]
}}
It has a 33-generation predecessor with 8 cells:
{{EmbedViewer
|pname = uturnerpredecessor2
|position = center
|viewerconfig = #C [[ GPS 10 THUMBSIZE 2 STOP 33 ]]
}}
there is also a 10-cell pattern that can appear that converges to the U-turner in 1 generation.
{{EmbedViewer
|rle = 3o$3o$2o$o$o!
|position = center
|viewerconfig = #C [[ GPS 4 THUMBSIZE 2 ]]
}}
Sometimes, a block will become a U-turner when it eats something but doesn't recover:
{{EmbedViewer
|rle = 4bobo$2obo2bo$2o2bo$6bo$6bobo!
|position = center
|viewerconfig = #C [[ GPS 4 THUMBSIZE 2 STOP 4 ]]
}}
The block can be restored with another block and a boat:

'''Zlife''', or '''B3/S234z''', is a [[non-totalistic cellular automaton]] first thoroughly described by [[Lucy D'Agostino]] on December 19, {{year|2023}}. It is similar to Life but differing with a 4z survival condition, which has the effect of making soups take longer to settle down.

==Still lifes==

All still lifes that work in [[Conway's Game of Life|Life]] work in this rule due to the addition of a survival condition, though the reverse isn't true. The simplest example of this is the Z-pentomino, which dies in Life but is stable in Zlife:

|rle = x = 3, y = 3, rule = B3/S234z
b2o$bo$2o!
|position = center
|caption = The Z-pentomino
|apgcode = xs5_174/b3s234z
}}

Oddly, the Z-pentomino is 18 to 19 times rarer than the boat across all soup symmetries, even [[Static symmetry#C2|C2_1]], its native symmetry.

The [[dead spark coil]] is much more common in Zlife due to the [[pi-heptomino]] evolving into one, plus a beehive. [[Hat]]s are more common as well.

==Spaceships==

All of the 4 most common spaceships from Life ([[glider]], [[LWSS]], [[MWSS]], [[HWSS]]) work in Zlife. In addition, there is an {{LinkCatagolue|xq16_21rgr90csje4/b3s234z|style=raw|name= 8c/16}} spaceship native to the rule.

Known speeds are c/2o, 2c/5o ([[44P5H2V0]]) c/3o, 2c/7o ([[Weekender]]), c/4o<ref name="post174338" />, c/5o ([[Snail]]), c/10o ([[Copperhead]]), c/4d and c/5d ([[58P5H1V1]])

===Puffers===
Some puffers are known to exist in Zlife, like [[Puffer 2]] a {{LinkCatagolue|yl60_1_3_45eef466630ec5f1ff7ea0399db515bc/b3s234z|style=raw|name= naturally-occuring p60 blinker puffer}}, as well as some high-period c/2o puffers.<ref name="post174322" />

==Oscillators==
Most small oscillators from Life work in Zlife, though higher-population and higher-period ones are less likely to work.
Some oscillators native to Zlife are known, such as this p58 statorless century hassler:

{{EmbedViewer
|rle = x = 12, y = 5, rule = B3/S234z
2o$obo6bo$b2o6b2o$2bo6bobo$10b2o!
|viewerconfig = #C [[ AUTOSTART ZOOM 12 GPS 20 ]]
|position = center
|apgcode = xp58_35ey2eko/b3s23
}}

The existance of oscillators of periods 64+ has been proven using [[Snark64]] loops, but the question of if Zlife is omniperiodic remains unanswered.

===Guns===
The [[Gosper glider gun]] and the [[p4-assisted period-28 glider gun]] both work in this rule.

==What is a U-turner?==
The [[U-turner]] (or '''U''' in conduit names) is a somewhat common methuselah in [[Conway's game of life]]. Even though it was discovered in [[1971]], it wasn't until May 2021 that it was recognized as a distinct object.
==Conduits and converters==

==Predecessors==
Like all patterns in [[Conway's Game of Life]] (except for [[Gardens of Eden]]), the U-turner has many predecessors. obviously, not all of them can be listed, so here are some of the more useful or notable ones.
===Still life+methuselah reactions that make U-turners===
Reactions are grouped by the still life involved

===Other predecessors===
The U-turner has one six-cell predecessor:
{{EmbedViewer
|pname = uturnerpredecessor
|position = center
|viewerconfig = #C [[ GPS 10 THUMBSIZE 2 ]]
}}
It has a 33-generation predecessor with 8 cells:
{{EmbedViewer
|pname = uturnerpredecessor2
|position = center
|viewerconfig = #C [[ GPS 10 THUMBSIZE 2 STOP 33 ]]
}}
there is also a 10-cell pattern that can appear that converges to the U-turner in 1 generation.
{{EmbedViewer
|rle = 3o$3o$2o$o$o!
|position = center
|viewerconfig = #C [[ GPS 4 THUMBSIZE 2 ]]
}}
Sometimes, a block will become a U-turner when it eats something but doesn't recover:
{{EmbedViewer
|rle = 4bobo$2obo2bo$2o2bo$6bo$6bobo!
|position = center
|viewerconfig = #C [[ GPS 4 THUMBSIZE 2 STOP 4 ]]
}}
The block can be restored with another block and a boat:

==What is a U-turner?==
The [[U-turner]] (or '''U''' in conduit names) is a somewhat common methuselah in [[Conway's game of life]]. Even though it was discovered in [[1971]], it wasn't until May 2021 that it was recognized as a distinct object.

==Predecessors==
Like all patterns in [[Conway's Game of Life]] (except for [[Gardens of Eden]]), the U-turner has many predecessors. obviously, not all of them can be listed, so here are some of the more useful or notable ones.
===Still life+methuselah reactions that make U-turners===

===Other predecessors===
The U-turner has one six-cell predecessor:
{{EmbedViewer
|pname = uturnerpredecessor
|position = center
|viewerconfig = #C [[ GPS 10 THUMBSIZE 2 ]]
}}
It has a 33-generation predecessor with 8 cells:
{{EmbedViewer
|pname = uturnerpredecessor2
|position = center
|viewerconfig = #C [[ GPS 10 THUMBSIZE 2 STOP 33 ]]
}}
there is also a 10-cell pattern that can appear that converges to the U-turner in 1 generation.
{{EmbedViewer
|rle = 3o$3o$2o$o$o!
|position = center
|viewerconfig = #C [[ GPS 4 THUMBSIZE 2 ]]
}}
Sometimes, a block will become a U-turner when it eats something but doesn't recover:
{{EmbedViewer
|rle = 4bobo$2obo2bo$2o2bo$6bo$6bobo!
|position = center
|viewerconfig = #C [[ GPS 4 THUMBSIZE 2 STOP 4 ]]
}}
The block can be restored with another block and a boat:

==Predecessors==
Like all patterns in [[Conway's Game of Life]] (except for [[Gardens of Eden]]), the U-turner has many predecessors. obviously, not all of them can be listed, so here are some of the more useful or notable ones.
===Still life+methuselah reactions that make U-turners===

===Other predecessors===
The U-turner has one six-cell predecessor:
{{EmbedViewer
|pname = uturnerpredecessor
|position = center
|viewerconfig = #C [[ GPS 10 THUMBSIZE 2 ]]
}}
It has a 33-generation predecessor with 8 cells:
{{EmbedViewer
|pname = uturnerpredecessor2
|position = center
|viewerconfig = #C [[ GPS 10 THUMBSIZE 2 STOP 33 ]]
}}
there is also a 10-cell pattern that can appear that converges to the U-turner in 1 generation.
{{EmbedViewer
|rle = 3o$3o$2o$o$o!
|position = center
|viewerconfig = #C [[ GPS 4 THUMBSIZE 2 ]]
}}
Sometimes, a block will become a U-turner when it eats something but doesn't recover:
{{EmbedViewer
|rle = 4bobo$2obo2bo$2o2bo$6bo$6bobo!
|position = center
|viewerconfig = #C [[ GPS 4 THUMBSIZE 2 STOP 4 ]]
}}
The block can be restored with another block and a boat:

Conduit

2025-02-11T15:03:29Z

C28:

{{Glossary}}
A '''conduit''' is an arrangement of [[still life]]s and/or [[oscillator]]s that move an [[active reaction]] to another location without themselves being permanently damaged. The chaotic object may be transformed into a different chaotic object in the process, but no permanent debris may be left behind. Alternatively, [[glider]]s or other [[spaceship]]s may be accepted as inputs and/or emitted as outputs; any emitted spaceships will either abandon the site of their creation, or can be absorbed by eaters. Probably the most important conduit is [[Conduit 1]], in which a [[B-heptomino]] is transformed into a [[Herschel]] in 59 generations.

==Herschel conduits==
{{main|Herschel conduit}}

The most prolific stable conduits are those which rotate, reflect or translate a [[Herschel]] in a certain number of [[generation]]s. Oscillators of all [[period]]s {{nowrap|≥ 57}} can be built using these [[elementary conduit]]s. All except the smallest [[stable reflector]]s use Herschel conduits, some of the counter-examples being the [[Snark]], [[rectifier]], and [[Boojum reflector]].

==B-heptomino and other conduits==

There are other conduits that move objects other than the Herschel, objects like the [[B-heptomino]], [[R-pentomino]], or the [[century]]. These conduits are no less useful than Herschel conduits, and some Herschel conduits are made up of two or more different conduits transforming the signal.

As of February 2024, there are 16 objects that are "officially" recognized as conduit signals. Those objects are:
* the [[R-pentomino]] (abbreviated as '''R''')
* the [[B-heptomino]] (abbreviated as '''B''')
* the [[Herschel]] (abbreviated as '''H''')
* the [[century]] (abbreviated as '''C''')
* the [[dove]] (abbreviated as '''D''')
* the [[pi-heptomino]] (abbreviated as '''P''')
* the [[queen bee]] (abbreviated as '''Q''')
* the [[wing]] (abbreviated as '''W''')
* the [[I-heptomino]] (abbreviated as '''I''')
* the [[two-glider octomino]] (abbreviated as '''O''')
* the [[blonk-tie]] (abbreviated as '''J''')
* the [[U-turner]] (abbreviated as '''U''')
* the [[E-heptomino]] (abbreviated as '''E''')
* the [[glider]] (abbreviated as '''G''')
* the [[lightweight spaceship]] (abbreviated as '''L''')
* the [[middleweight spaceship]] (abbreviated as '''M''')

The letter '''X''' is used as a placeholder, such as in [[G-to-X]].

There are also some objects that have some conduits which input or output it but are not considered to be "official" conduit signals, like the [[R-turner]], the [[heavyweight spaceship]], or "e9jp"<ref name="post149308" />.

The names of conduits that input and/or output an object other than a Herschel are derived from 3 things: the input and output object, the orientation of the output object relative to the input, and the amount of time it takes for the output to reach its canonical form. More specifically, the name is structured as follows:
<center> '''[abbreviation of the input object] [orientation of output object relative to the input object] [amount of time it takes for the output object to appear] [abbreviation of the output object]''' </center>

For conduits with symmetrical inputs (i.e. a [[pi-heptomino]] or [[queen bee]]) like [[PF35W]], an asterisk ('''*''') is used to denote that the conduit can be flipped to place the input either clockwise or counterclockwise. The resulting pair of conduits will have outputs in the same number of ticks, but they will be either F and Fx ('''F*'''), L and Rx ('''L*'''), R and Lx ('''R*'''), or B and Bx ('''B*''').<ref name="post66272" />

For conduits with both symmetrical inputs and outputs like [[PT8P]], the resulting pair of conduits will have outputs in the same number of ticks, but they will be either F and Fx ('''F*'''), L, Rx, R and Lx ('''T'''), or B and Bx ('''B*''').

So for example, take this conduit:
{{EmbedViewer
|pname = pf35w
|viewerconfig = #C [[ THUMBSIZE 2 ZOOM 8 GPS 15 ]]
|position = center
|style = width:300px;
}}

It takes a Pi-heptomino ('''P''') and in '''35''' generations it changes it into a Wing ('''W''') facing forward ('''F''') relative to the input, which makes this conduit '''PF35W'''.

==Creating a useful conduit==
To make it more likely that a new elementary conduit will be useful, the following should be true:
* The output should have enough clearance that it doesn't hit a catalyst before it can be perturbed.
* The input should have enough clearance that an object can get there. Some active objects, like B-heptominoes, usually come from certain directions, so make sure that direction isn't blocked.
* The input reaction is common enough. For example, there are a lot more [[U-turner]] input conduits than output conduits, but as more U-turner output conduits get found, the input conduits become more useful.
* The input and output reactions expand enough. [[Honey farm]]s don't expand much and don't have that much use in conduits (with some known exceptions, like composite honeyfarm-involving [[H-to-G]]s<ref name="post153842" /><ref name="post157909" /> or a potentially useful honeyfarm [[eater]] that works in all eight orientations<ref name="post147390" />). Similarly, [[lumps of muck]] may appear useful, but they expand symmetrically from the origin rather than moving in one direction and aren't used in conduits much.

Finding a conduit that outputs a given methuselah is generally harder than finding a conduit accepting a given input. There is no known efficient way to search for a specific output reaction, other than searching for any output and filtering by the output later.<ref name="post152146" />

For general help with finding new conduits, see [[Tutorials/Finding conduits]].

The '''water strider''' is a [[31c/240 orthogonal]] [[spaceship]] that was constructed on January 31, {{year|2025}} by [[FWKnightship]].<ref name="post202694" /> and reduced by several people over the next few days.

At 46259 cells and a 14021×7291 bounding box, it is the smallest known spaceship of this speed, and the smallest [[self-supporting]] spaceship of any kind by both population and bounding box, surpassing the [[leaf bug]] and [[waterbear]]. Its original form had 62887 cells. It is notable for being the first self-constructing spaceship that fits in a {{times|16384|16384}} [[LifeViewer]] window.

31c/240 orthogonal

{{Speed

}}
'''31c/240 orthogonal''' is an orthogonal [[speed]] equal to thirty one two-hundred-fortieths of the [[speed of light]].

In April 2013, [[Dave Greene]] discovered [[31c/240 Herschel-pair climber]], a glider-emitting [[reburnable fuse]] based on pairs of Herschels traveling along chains of blocks.<ref name="post7782" /> In January 2014, Kiho Park suggested a workable mechanism, allowing Herschel pairs to climb block chains while suppressing all output gliders.<ref name="post10293" /> Each passing Herschel shifts its block chain forward by 9 ticks, which is relatively prime to 31, so it is possible to shift the block chains by any desired distance. Thus a rake unit can be adjusted to output gliders on any desired lane. Arbitrary [[slow salvo]] recipes can be fired from the rakes, enabling a 31c/240 spaceship to construct its own support by sending LWSS and MWSS spaceships forward to collide with gliders at the front end, and extend the block chains ahead of the ship. The first spaceship built using this technology in September 2014 was the [[shield bug]], soon followed by the smaller [[centipede]]. In April 2016, [[Michael Simkin]] constructed [[centipede caterloopillar|a smaller 31c/240 orthogonal spaceship]] using [[caterloopillar]] technology<ref name="post30105" />, which was the smallest 31c/240 spaceship until May 9, {{year|2020}}, when the [[silverfish]], a self-supporting 31c/240 caterpillar-type spaceship designed using the slow salvo recipe from the centipede but a simpler front end, was completed.<ref name="post96462" /> On December 27, {{year|2024}}, the 75961-cell [[Leaf bug]] was constructed.<ref name="post200518" />

31c/240 had been the slowest speed achieved by orthogonal spaceships until March 5, {{year|2016}}, when [[copperhead]] was discovered.

A '''H-to-MWSS''' is a [[Spartan]] (using an [[eater 1]] instead of the [[7×9 eater]]) [[converter]] found by [[Tanner Jacobi]] in October {{year|2015}},<ref name="post23888" /> which converts an input [[Herschel]] to a middleweight spaceship. The key discovery was a very small but slightly [[dirty]] H-to-MWSS conduit (shown below), where a Herschel is catalyzed to produce an [[MWSS]] but also leaves behind a [[beehive]]. Prefixing two [[R64]] conduits to this produces a [[composite]] converter that successfully deletes the beehive in advance, using the input Herschel's [[first natural glider]].

The repeat time is 157, but it can be reduced to 72 using the variant below (or other variants, if not required to be spartan).

Below is the spartan glider-to-MWSS converter used in the [[Orthogonoid]]:

It consists of a [[syringe]], [[Lx200]], [[L112]], [[L156]], HLx141B, [[BRx46B]], [[BFx59H]], [[R64]], [[Snark]], [[Eater 1]] and the hive-laying H-to-MWSS converter (with the hive deleted by the glider from the HLx141B which travels through the [[Snark]] and [[Eater 1]]).

The infobox pattern contains initial [[ghost Herschel]]s marking the three Herschel (or [[Herschel great-grandparent]]) locations in the H-to-MWSS conduit. The pattern also includes a common way of reaching the input Herschel by prepending an [[Fx77]], but that additional conduit is not a necessary part of the H-to-MWSS. In the pattern shown in the infobox, a "ghost" [[MWSS]] marks the output location.

There are many other ways to remove the unwanted beehive using a spare glider or additional conduits, but they are generally less compact than this.

==Other H-to-MWSS converters==

On November 18, {{year|2024}} [[AlbertArmStain]] found a different H-to-MWSS, which had a smaller bounding box, though with a higher repeat time of 141 ticks and a higher population count.<ref name="post198122" />

Later that same day, 2 different reductions were found by [[Period1GliderGun]] and [[Lucy D'Agostino]], both of which reduced the repeat time to 120 ticks.<ref name="post198124" /><ref name="post198137" />

'''HFx58B''' is a common [[Herschel]] to [[B-heptomino]] converter found by [[Paul Callahan]] in 1997. It is used as the first stage of [[F117]] and many other [[Herschel conduit]]s. There are two common variants, both shown in the pattern in the infobox, with "ghost" B-heptominoes and "ghost" [[BFx59H]]'s marking the output locations. By adding a [[bouncer]], a periodic Fx78 can be made as shown in the infobox.

'''54P23''' is a {{period|23}} [[oscillator]] and [[honey farm hassler]] discovered by [[Nico Brown]] on November 6, {{year|2022}}.<ref name="post153183" /> It is the fifth unique period-23 oscillator to be discovered. With only {{cells|55|text=55 cells}} in its original minimum phase, it was the smallest known oscillator of its period,<ref name="post153184" /> surpassing [[70P23]] which was discovered just two days earlier.

On November 7, {{year|2022}}, [[GUYTU6J]] found a {{gliders|26}} synthesis.<ref name="post153193"/> On December 13, {{year|2023}}, [[Chris857]] lowered the cost to {{gliders|25|text=25 gliders}}.<ref name="post173163"/><ref name="j5740541142"/>

On March 3, {{year|2024}}, [[Period1GliderGun]] reduced the population to 54 cells from the original 55,<ref name="post179639" /> by noticing that a blinker could replace the block catalyst. The blinker is rephased with each cycle.

== LCM oscillators ==
The [[LCM oscillator]] below is shown due to being the smallest known one by population while also satisfying the condition that at least one cell oscillates at the full period.

C28: how do you say "please don't ever cook again" in a professional manner?

[[Category:Main page templates]]
* '''November 3''': [[AlbertArmStain]] [https://conwaylife.com/forums/viewtopic.php?f=2&t=1849&start=925#p198122 posts] a new [[H-to-MWSS]] conduit to the ConwayLife forums. A couple of minutes later, [[Period1GliderGun]] [https://conwaylife.com/forums/viewtopic.php?p=198142#p198124] and [[Lucy D'Agostino]] [https://conwaylife.com/forums/viewtopic.php?p=198142#p198137] each post their own reductions to it, both of which reduce the population to 58 cells (down from 65 cells) and the repeat time to 120 generations (down from 141 generations).

C28: /* Still lifes */

{{Rule
|name = Zlife
|imgname =
|char = Chaotic
|b = 3
|s = 234z
|animated = true
|reversal = B01234-z78/S01234678.
}}

'''Zlife''', or '''B3/S234z''', is a [[non-totalistic cellular automaton]] devised by [[Lucy D'Agostino]] on December 19, {{year|2023}}. It is similar to Life but differing with a 4z survival condition, which has the effect of making soups take longer to settle down.

==Still lifes==

All still lifes that work in [[Conway's Game of Life|Life]] work in this rule due to the addition of a survival condition, though the reverse isn't true. The simplest example of this is the Z-pentomino, which dies in Life but is stable in Zlife:

{{EmbedViewer
|rle = x = 3, y = 3, rule = B3/S234z
b2o$bo$2o!
|position = center
|caption = The Z-pentomino
|apgcode = xs5_174/b3s234z
}}

Oddly, the Z-pentomino is 18 to 19 times rarer than the boat across all soup symmetries, even [[Static symmetry#C2|C2_1]], its native symmetry.

The [[dead spark coil]] is much more common in Zlife due to the [[pi-heptomino]] evolving into one, plus a beehive. [[Hat]]s are more common as well.

==Spaceships==

All of the 4 most common spaceships from Life ([[glider]], [[LWSS]], [[MWSS]], [[HWSS]]) work in Zlife. In addition, there is an {{LinkCatagolue|xq16_21rgr90csje4/b3s234z|style=raw|name= 8c/16}} spaceship native to the rule.

{{EmbedViewer
|rle = x = 56, y = 12, rule = B3/S234z

obo10bobo15bo$51b2ob2o$51bo$52bo!
|viewerconfig = #C [[ THUMBSIZE 2 ]]

}}

Known speeds are c/2o, 2c/5o ([[44P5H2V0]]) c/3o, 2c/7o ([[Weekender]]), c/4o<ref name="post174338" />, c/5o ([[Snail]]), c/10o ([[Copperhead]]), c/4d and c/5d ([[58P5H1V1]])

===Puffers===
Some puffers are known to exist in Zlife, like [[Puffer 2]] a {{LinkCatagolue|yl60_1_3_45eef466630ec5f1ff7ea0399db515bc/b3s234z|style=raw|name= naturally-occuring p60 blinker puffer}}, as well as some high-period c/2o puffers.<ref name="post174322" />

==Oscillators==
Most small oscillators from Life work in Zlife, though higher-population and higher-period ones are less likely to work.
Some oscillators native to Zlife are known, such as this p58 statorless century hassler:

{{EmbedViewer
|rle = x = 12, y = 5, rule = B3/S234z
2o$obo6bo$b2o6b2o$2bo6bobo$10b2o!
|viewerconfig = #C [[ AUTOSTART ZOOM 12 GPS 20 ]]
|position = center
|apgcode = xp58_35ey2eko/b3s23
}}

The existance of oscillators of periods 64+ has been proven using [[Snark64]] loops, but the question of if Zlife is omniperiodic remains unanswered.

===Guns===
The [[Gosper glider gun]] and the [[p4-assisted period-28 glider gun]] both work in this rule.
