That's because it's not "game of life jargon", it's "cellular automata" jargon. Which is a field of math and comes along with a bunch of math jargon from related fields.
mmmh I don't think so. I've read several papers on cellular automata and I don't recognize the terms
I searched several of these terms and they are all specifically jargon of game of life enthusiasts, (i.e. search reaults are all on fansites related to game of life) not general cellular automata jargon.
