This has a fairly prominent domino spark. Here are some p8 (left) and p16 (right) toad hasslers:
x = 95, y = 58, rule = B3/S23
...

I'm not sure if there is any other current use for this spark.


On a side note, this combination of a pi and T I discovered a long time ago. It is a methuselah, which stabilises in 946 generations. I know it can be synthesised with three gliders but I don't know how:
x = 3, y = 10, rule = B3/S23

Has anyone turned the 2c/3 signal into an oscillator before? Here's a p7 signal generator I found.

Did you find this with Dean Hickerson's drifter search program? There is a collection of signal injectors found by Dean here. There is also this p11 double-length signal injector that I found a while back:

WLS, actually. I'm guessing Dean HIckerson used his drifter search program to find the p17 oscillator back in '97?

Well, according to http://www.conwaylife.com/wiki/List_of_ ... till_lifes it is not common, as it is not listed there. Could you give an example of a reaction, which produces this still life?

It always seemed really strange to me that so many structures designed for standard 2c/3 signals also work just as well for double-length signals. I just checked that the standard-signal eater on the p7 injector also works for double-length signals -- see below.

I don't know if Dean Hickerson's 2c/3 elbow is commonly known: it converts a standard signal to a double-length signal, though not fast enough to handle a p7 input of course! If it were possible to suppress two out of three of the signals somehow, you could turn a corner every 21 ticks:

It only works for one corner, though, since there's no known way to get back to a standard signal from a double-length one -- you'd have to convert back to gliders or Herschels and build a standard-signal recipe starting from scratch.

Yes, the vast majority of known billiard tables were found with dr (Deans drifter program). dr has found an oscillator for every period up to 22 except 19:

I think this is an important point for anyone trying to find a signal turner. The double-length signal seems to be about as common as the single length signal, so it would likely be beneficial to try starting a search with the double-length signal. Here is another pattern (left) that has the same double-length-signal-producing reaction as the failed signal turner (right). (compare the reactions starting at generation 16):
x = 34, y = 33, rule = B3/S23

Unfortunately, this other drifter doesn't seem to be useful in any way.

I found this 17 cell methuselah that unfortunately only runs aroun 4K generations but I thought was neat:
x = 15, y = 16, rule = LifeHistory
5C$.C.C$.C.C$.C.2C10$13.C$12.C.C$12.2C!

The ship ends up roughly quadrupling the longevity, but the lifetime is not very long compared to other 17 cell patterns.

I also found this pattern that fits in a 10x20 bounding box that lasts roughly 7700 generations and produces a shillelagh:
x = 10, y = 20, rule = B3/S23
o2bo3bobo$obob5o$bob2o3bo$b2ob2ob2o$2bo3b3o$b4o3b2o$o4b2ob2o$obobo$2b

Very interesting reaction there; might be possible to tease a better stable MWSS-output conduit out of it? The basic reaction is an R catalyzing a loaf into the MWSS:
x = 6, y = 17, rule = B3/S23

The sacrificial block might be replacable with a catalyst, not sure though. But even if it's not, this is still a "unimolecular" synthesis.

Obviously they are new, great! There must be a wealth of c/6 technolgy out there waiting to be discovered, although this is cumbersome.

We still lack a useful spark to build more complex structures. Keep on searching for something similar to the c/5 spider based technology.

That first c/6 pushalong uses a component found in much of the known c/6 technology. Also, The first pushalong can support (in two different ways) a small tagalong I found a while back:
x = 41, y = 55, rule = B3/S23

10b2o!

Of course, this tagalong also uses that same common component. I think it might be worthwhile to perform a search of all possible height-10 c/6 spaceships that start with that component. I have already searched (i think) completely up to a height of 9 for c/6 orthogonal spaceships, but I would like independent confirmation before I claim that no height-9 ships exist.

I have completed the searches for width (height?) 9 and 10 for c/6 orthogonal spaceships (with a version of gfind.) EDIT: retracting the above statement about what searches I've completed. Found some bugs in my code.
In fact, the pushalongs I posted came from partial patterns in the width 10 search.

I finally found this after posting an already-discovered pattern to the LifeWiki :lol: Anyway, I read on the wiki that the smallest known glider synthesis of the R-pentomino contains 3 gliders; I looked this up because I had found one with 2 gliders. Here's the plaintext file:

O
.OO
OO..OO
.....OO
....O


This is probably really stupid in some way that I don't know (new to the Game of Life thing) but yeah, it might just be something interesting.

The problem with that two-glider synthesis is that the gliders can't actually come from far away and get to those locations. If you "rewind" the gliders by one tick, you'll see that they interact in the previous generation -- so you end up with a traffic light instead of an R-pentomino.

So I guess what you've discovered is an important but annoying rule about glider constructions: gliders are really good at finding ways to interact before they're supposed to...!

Ah, thanks for the info ^^' Now to actually attempt to find REAL new patterns :lol:
My (idiotic) mistakes lead me to the idea of a sort of pattern-oriented Life simulator. This has probably been done before, but I happen to be a programmer. I think it's a good project to take on. :P

Hi, I'm new and have been playing for a couple of months now, and I think I've found something that's interesting enough to go on this page :D . It's A symmetrical methuselah (5 x 15, pop = 15) that stabilises at gen. 4918, (pop = 1632). There should be a way to alter it so that it lasts longer when not symmetrical, and I don't know if the 12 cells on the left are the minimal for creating the pattern needed.
Please note that I could have been an idiot because I didn't bother looking if anyone else had discovered this before... :D
Now, I don't know if golly can load this type of code, but I'll give an image of it below this

A simple predecessor of house bridge boat (found in symmetrical soup).
x = 22, y = 8, rule = B3/S23

Just a quick note, I'm retracting the above statement after I discovered some problems in my code.

Hello to all

I worked on some "improvements" to the Gosper Glider Gun and like to share with you, I wonder if it's something new.

number 1 I would like to show you is: "improved gosper gun "

this is a double barreled pseudo p15 Gosper glider gun

thanks
Herik
