Re: Miscellaneous Discoveries in Other Cellular Automata

This morning, after coming back from holiday, I proved greycells/OffNeutronium/ExtendedLifeButNotAsGood omniperiodic. I'm quite happy with this result, especially considering the time I spent soup searching, and considering how close this rule is to Life - maybe some of the higher period oscillators...

That's because 21-bit still lifes are surprisingly common, and so are not considered notable. I think the discoveries page contains still lifes greater than 32 bits, but I could be wrong there.
