Spindrift Rulespace (cardinality 28, around B2n3-qy4eqy6n7c/S2-n3-a4atz5k)

[Rhombic]

Rulespace defined by B2n3-qy4qy(4cejkt5e6ckn78)/S2-n3-a(-k)4atz(4ce5cekny6acein78)
or, in partial notation (note that 8s are optional):
pB2n3aceijknr-qy4qy-ainrwz5-acijknr6-aei78S2aceik-n3ceijnqr-a4atz-ijknrwy5-aijr6-k78

The "type rule" is B2n3-qy4eqy6n7c/S2-n3-a4atz5k

(maybe it's worth it to narrow it down more, like at most N transitions away from the type rule, but I'm not sure how to do it or if it makes much of a difference)
These 2^28 rules contain very interesting dynamics for high-period oscillators and spaceships as well as complicated puffers and rakes with wildly differing mechanisms depending on the rule. They have high engineering potential just from the sheer numbers of sparky objects but also have many endemic or near-endemic patterns.

From a previous post in Misc Disc O C A:
