The 17-bit object (bottom right) represents another possible start. Is its synthesis known? It doesn't seem trivial to me. Here is the synthesis for a similar still life. Unfortunately I had to use the loop instead the hat, because the hat component is not stable in the last reaction :( x = 164, y ...

Playing around with Bellman and the input file for the snark, I've found this honey farm predecessor to LoM converter, emitting a glider. This is probably of no use.

Hello, all, It is written everywhere that David Buckingham has found glider syntheses for all still lifes up to 14 cells, but I couldn't find the full database in the Internet. The best open database I could find is the one of Mark Niemiec , but it lists syntheses only for still lifes up to 13 cells...

Having analyzed gencols' source code, I concluded, that it uses "spaceship" sensu stricto. I modified the source code so that it traced periodic patterns up to the 20th generation --- ../../gencols/output.c 2012-04-15 11:12:57.708179920 +0200 +++ ./output.c 2012-04-15 13:01:04.882425235 +0200 @@ -62...

I'm trying to learn how to use gencols. Perhaps I don't understand something really basic. Say, I want to find a collision of Puffer 2 with a spaceship, that would transform it into a spaceship (i. e. finding Ecologist is the expected result). I've created a pattern puffer2.life *..* ....* *...* .**...

A pentadecathlon appears in the ash. x = 8, y = 5, rule = B3/S23 2o$o$o$bo4b2o$6bo! It's a simple pi-heptomino block explosion so I guess it's not new. I find it interesting, though... This reaction has been known since 1971 (see Lifeline Vol. 4) A glider colliding a mango precedes it. x = 8, y = 5...

I've found a twin B heptomino puffer, but B-heptominoes are arranged in a different way than here . x = 5, y = 25, rule = B3/S23 o2bo$4bo$o3bo$b4o4$o$b2o$2bo$2bo$bo2$bo$2bo$2bo$b2o$o4$b4o$o3bo$4bo$o 2bo! Also I've found two variants of more compact debris for it. x = 49, y = 35, rule = B3/S23 18b3o$...
