Equally useless: at time 30, the active region is an inward-facing edgy bookend-producing octomino about to hit a beehive. At time 57, the SAME inward-facing octomino (shifted) attacks the active region.

Precisely. It is the very "temperature of chaos" metric that makes michelife9 so intriguing, I feel. On a 50% soup in a torus, you get large patches of Life and Antilife battling for control of the thermostat, as it were.
It might be illuminating to expand this into an equivalent 4-state rule with ...

It's actually making a B-heptomino (technically, its child), complete with its inconvenient initial block.

Try running it until you get past generation 63, then use the “step back” button to get back to 63

Sadly I don’t think I can reproduce it
I had the same thing happen some time in the mid-50s (just after the second LWSS formed). I tried to see how it formed, so I tried to back up, and it just ...

Are you saying there are 2^25 possible period 2 oscillators and period 2 rotor configurations ? I haven't found this on wiki yet and you say you add higher period oscillators like period 17 or period 23, they must have 2^10000 possible rotor configurations. Why add them ?

No. There are 2^25 ...

What's curious about this rule is that even though stable crusts tend to occur whenever foam hits a vacuum, even though these crusts are extremly durable, they are not completely impenetrable. One occasionally sees stable islands forming and then vanishing later, or chunks being taken ...

This is a new p2 oscillator , right ? Someone make a new page for this :)
There are exactly 6596 21-bit period 2 oscillators, determined by exhaustive computer search. (That's as high as anyone has actually counted so far). The reason that there are so many is that in periods 2 patterns, every ...

I realized something... many newcomers (mistakenly) think that the LifeWiki contains all known information about CGoL, even things like random still lives, P2s, medium-lived methuselahs etc.
Why is this the case?

One thing that is fairly common among wikis in general is that they don't include ...

Running this for 100+ generations then pressing Ctrl-Z causes the active region to turn into a tub.

It seems to depend on what steps you use. E.g. if I step every 20 until 200, repeatedly pressing Ctrl+Z works fine until 120. Then, at 100 the bottom is just a tub, then at 80 it's a tub and a ...

I guess it depends on what you mean by "known". That particular constellation of blocks probably hasn't been used to make that particular spark before. But it's a well-known spark, and various octohash searches will turn up dozens or hundreds of ways to make that spark ...

This is a fairly simple rotor; I would be surprised if it wasn't already known. The stator can also be reduced:

The two 1x5 lines alone would do that, without needing any of the other bits. Each of those forms a solid 3x3 block, and both solid and hollow 3x3 blocks form pre-pre-traffic lights in 2 generations, and full traffic lights 2 generations later. If two ...
