Replicators: B37/S345

I found this replicator on Oct. 20, 2001. It repeats every 35 generations, on a one-dimensional 6-unit grid.

Along with several less-interesting oscillators, this rule has a period-29 oscillator, which somehow resembles a thwarted pair of replicators:

Jason Summers quickly found a way to confine a set of replicators behind a pair of period-5 oscillators:

B37/S345 also has a few interesting spaceships including a very small c/2 spaceship.

It is unknown whether the replicator can lead to high-period spaceships, guns, or other interesting technology.
