It appears to be an unnoticed variant of caterer on figure eight with a smaller bounding box than the known version. Nice observation!

That's actually a fascinating slow 8c/364 fore/backrake for the 52c/104. Slow bidirectional rakes like this are very easy to confuse for guns in my experience.

Rephasing the GGGs allows the reflector to be brought in one cell diagonally, shaving off one column: x = 53, y = 37, rule = LifeHistory 5.2A19.2BA3B4.B$4.B2AB16.2BABA10B$4.3B5.4B2A.B2.2B2A13B10.2A$5.3B2.5B A3BA4B2A12B2A10.A$5.9BA5BA2B.2A10B.B2A9.A$4.10BA3BAB2A4BABA5B4.B8.A2. 3A$4.BA2B.5BA5BA7BA3B13...

Help

A useful identity here that may help: f(x)^g(x) = e^(g(x)ln(f(x)) — because f(x)^g(x) = e^(ln(f(x)^g(x))), which can be expanded using the properties of logarithms.
