Can I have a trusted flag, please? There's a theorem about phoenixes that I want to add a citation for.

Re: Euclidean CA (ECA)

A cell with maximum heat would be surrounded by infinitely many cells. This 'maximum heat' number is finite, but I do not yet know its value. A 511x511 block of cells yields the number 6.0267726589419..., but that's not even close to a good estimate. I have settled on using 7 when engineering day a...

Re: image oscillator?

It would be an oscillator if you could construct a rule it works in. Unfortunately, that doesn't appear to be possible, even with extended neighborhoods. See, when the dot hits one of the circles, it gets eaten. This means that the circle goes back into a steady state and has no reason to emit a do...
