Synthesis

In January 2000 Mark Niemiec found a 21-glider synthesis of this oscillator.[1] On August 25th 2016, Goldtiger997 found a 10-glider synthesis of odd keys, which was later reduced to 9 gliders by Dave Greene.[2]

gollark: Yes, I know.
gollark: I guess that's probably doable with regular player privileges and /home.
gollark: If lemmmy can teleport stupidly fast, I demand the same ability, since you make it sound like it's being used for actual gameplay.
gollark: *cheats*
gollark: It *waits* for *all* of them to finish.
