So if I want to have B3, I have to list every neighborhood of 3? Is there any way to simplify it with variables?

The start of the next year actually, or a few months after. (I'm looking at you, testitem.)

The question is not why B2a rules have a tendency to create Sierpinski triangles but why they have more replicators (which is pretty obvious: a line of 2 cells keeps going in the same direction, allowing it to potentially eventually create another one).

Its a very interesting rule which Kellie Evans named as the LtL rule with the most interesting dynamics in her thesis, but for some reason it seems no one has investigated it further.

I tried to use apgsearch on the rule, but it didn't seem to get anywhere on my computer. Most small patterns in the rule stabilize, except for one somewhat common exploding pattern, which causes most large-enough soups to never stabilize.

Any help would be much appreciated!

Well, it's not just replicators that form them either, in the second example, an object is puffing tubs and barges in the shape of a Sierpinski, so what explains that?

I'm confused. How is that not a replicator? A replicator creates copies of itself. That pattern creates copies of itself.

A non-monotonic spaceship is basically a spaceship whose frontend falls back in some generations. Such spaceships must have a period of at least 3.
