It's nice, but the name refers to the 2-state version. So we have a messy puffer in a 4-state version of Live Free or Die.

Pi becomes a 13c/43 block puffer:

Removing B8 kills the puffer, but keeps other patterns:

EDIT:
Running apgsearch on B3-r4y5r6a/S234jz5n in C1 (due to the lack of pi puffers; B3-r4y5r6a8/S234jz5n should be much slower); looking for patterns that work in both rules.

adding S5c keeps most of the interesting stuff (gun breaks) but removes the common big rake, making it much less explosive.

Known oscillator periods in this rule include, at least, 1, 2, 3, 4, 5, 6, 8, 10, 12, 14, 16, 24, 34, 40, 70n, 88, 96, 102, 264, and 1496. Some other multiples of 34, 88, or 96 could potentially work. Any others? Running apgsearch in different symmetries could find some.
EDIT 2: Periods 1056 and 1632 are definitely possible as LCMs (88, 96) (34, 96). Running apgsearch in D4_+2 to find symmetric patterns.
EDIT 3: Having trouble running apgsearch, seems to have difficulty getting started.

I've tried finding faster ships, but all results have come up negative, including any C/4s in a 40x40 box. I'm not sure if C/5 is the speed limit definitively, but it seems likely. If anyone would be able to prove or disprove that, I'd be interested to see.
