Re: Patterns that only work in 1 rule

There is a wiki article " endemic " which I believe describes what you are describing. There are categories for endemic patterns both with respect to outer totalistic rules and with respect to isotropic rules . For outer-totalistic, Figure eight on pentadecathlon is the smallest (24 cells) I could f...

I mean it adds one to the amount of times the SE lane has to eat a block pull to generate the NW block. The SE lane has to pull the block an extremely large amount of times to the diehard, but when it reaches it, it gets eaten once. If I'm understanding dvgrn's description correctly, the NW lane on...
