Re: Small predecessors of common objects and evolutionary sequences

I just added a bunch of still lives to the list. Please let me know if I made any errors or omitted any predecessors with minimal population. Looks mostly good to me, although I didn't go through to check every single predecessor if I knew of multiple at a given minimum population. Here's an 8-cell...

A B-heptalet predecessor can be hassled with period four.

Nice, that's smaller than my stabilization! That's a really nontrivial little catalyst-y reaction.

Nice! I know I found that catalyst at one point but I definitely don't remember finding anything that simple to react with it.

Re: Thread for basic non-CGOL questions

Why is (11,10)c/22 easier to find than 9c/10? Both seem to be past the 5c/6 horizon, but (11,10)c/22 is even closer to the speed limit than 9c/10. Because (11,10)c/22 is only close to the vacuum speed limit, whereas 9c/10o is close to the information speed limit. So for 9c/10o there's no way for in...

Since it seems as though Fano is down permanently (has been since late 2018), would it be possible to import the offline version of the glider database into Catagolue under some sort of pseudosymmetry for rules it applies to?

Just asking, can anyone search for a P3 strong dot sparker? Sadly, I believe it's all but confirmed by countless unsuccessful searches that those aren't actually possible.

Reporting this as it is essentially a copy of my poll. Please just stop reporting posts — you clearly don't have a good enough sense of what needs mod attention and what will just anger mods further.

With all due respect, I don't think it's really our place to be making polls like this... these options seem like they're just things you came up with and foisted on the community without discussing anything first, whereas ideally we would need a clear consensus among both moderators and a large sub...

I view the free will theorem in the opposite way you do. You go, "If experimenters have free will to choose measurement bases, then the measured particles must have free will.
