Despite the resemblance of the rules to Life's (differing only in B5 and S6), none of the usual life gliders and spaceships seem to work here. But the reason I started looking at B35/S236 was its small 2c/5 glider, which arises spontaneously from a lot of reactions:
There are also other 2c/5 spaceships (the second one below has period 10):
Many large c/2 spaceships:
Several large c/3 spaceships:
c/4, c/5, c/6, and 3c/7 spaceships, and a c/4 diagonal (glide-reflect) spaceship:
All three 2c/5 spaceships, and the c/6 spaceship, can be shot from guns. Many higher-period c/2 spaceships can be made using Jason Summers' puffer constructions.
