Many of these rules take place in a rulespace characterized by two common active objects: the B-pentomino, which commonly arises from the first generation of the R-pentomino, as well as this... err... uh... spinny thing. (EDIT: I checked to see if this was known and this appears ...

I tracked the evolution of the B-heptomino in all rules one transition from B3aiq4z5j6n7e/S2-ci3-aeky4itz5acin6c. (EDIT4: To be clear, I kept out all the boring ones. Some of them either die out quick or continue to form a p88 RRO like in the base rule.)

I think there's something wrong with your code tags...

The B-heptomino becomes a p56 RRO that feels like it should be loopable, but isn't.
