Looks a bit like a queen bee (without stabilising blocks), period 168 if I've counted correctly. Is this known about, and if so does it have a name? Just interested.

-- Oscar is an OSCillation AnalyzeR for use with Golly.

-- This script uses Gabriel Nivasch's "keep minima" algorithm.
-- For each generation, calculate a hash value for the pattern. Keep all of
-- the record-breaking minimal hashes in a list, with the oldest first.
-- For example, after 5 generations the saved hash values might be:
--
-- 8 12 16 24 25,
--
-- If the next hash goes down to 13 then the list can be shortened:
--
-- 8 12 13.
--
-- If the current hash matches one of the saved hashes, it is highly likely
-- the pattern is oscillating. By keeping a corresponding list of generation
-- counts we can calculate the period. We also keep lists of population
-- counts and bounding boxes to reduce the chance of spurious oscillator
-- detection due to hash collisions. The bounding box info also allows us
-- to detect moving oscillators (spaceships/knightships).
