B1e4t6i/S12i3

[KittyTac]

Like Platoon, it's a rule that is best viewed on a 1500x1500 torus. Chaos eventually gives way to stripes agar. Blocks are completely indestructible.

I’ve seen similar behavior in B3/S0123, which also settles into stripes agar, but more quickly (except for phase offset boundaries):

I'm not sure rules like this, with extremely limited potential for discovery, would require their own topic - I would personally put them in "Rules with interesting dynamics" and if someone found something very unique or explorable in one of them, then that is a good starting point.

In any case, the stripes agar arising without B3 interactions is surely notable!
