Octagon 2 (xp5_idiidiz01w1)

#C [[ GRID THUMBLAUNCH THUMBSIZE 2 THEME Catagolue ]]
x = 1, y = 1, rule = B3/S23
b!
This pattern is an oscillator.
This pattern is periodic with period 5.
This pattern runs in standard life (b3s23).
The population fluctuates between 16 and 24.
This evolutionary sequence works in multiple rules, from b3aijs2ckn3nqy through to b2-ae34-ew56-n78s01c234-ar5-j678.

by super common I mean more common than the hat (which is a p2 oscillator)

Super common in the pond life variant B36i/S2-i34j5i. Why is that?

In B2k3-eq8/S2-i3-q4ce8, this evolves slightly differently, but still has the same apgcode.

These are much more common in B3/S234w, as the octomino that normally turns into a fleet instead evolves into the octagon.

With relevance to the previous comment, it can interact with both because a snacker is a pentadecathlon with eaters. It can also interact with a HW emulator or any HW emulator variant with domino sparks. As this implies, it can interact with most domino sparkers.

Actually, I lie. There's a third isomer:

I imagine these are the only three isomers of Figure-8-on-pentadecathlon, since there's a functorial correspondence between them and the naturally-occurring p120 oscillators in the symmetric b3s23/D8_4 census.

As far as I know, there are two isomers of Figure-8-on-pentadecathlon, both of which should be around 1000 times more common than the 'nice p40' you suggested.

x = 22, y = 8, rule = B3/S23

I imagine we should start seeing these around the 10^14 mark.

Of course, we'll probably see a Figure-Eight-on-Pentadecathlon by then.

It can interact with a Figure-Eight in the same way as the fumarole, creating a nice P40 that might occur soon!

Hmm... It can interact with a fumarole's spark, but the fumarole seems too rare to have that happen any time soon.

Are there any ways this can interact with another object?
