117P9H3V0
117P9H3V0 is an orthogonal c/3 spaceship discovered by David Bell in May 1992.[1] It is based on a period-3 spaceship with a loosely connected back component which could be removed to form a period-9 spaceship, being the first spaceship of this period to be found. The back part creates a blinker, which is deleted later. In September 1997 Bell found a smaller period-3 component to support the period-9 trailing edge. In June 2001 Paul Tooke found a much smaller period-9 spaceship, 55P9H3V0.

gollark: Hey, I have a neat idea, I could make nginx output its traffic logs as JSON, and then dump these into some analysis scripts.
gollark: This one has traffic patterns closer to a real user.
