64P2H1V0 is an unnamed c/2 orthogonal spaceship discovered, along with several other period-2 spaceships, by Dean Hickerson on July 28, 1989. Although Hickerson does not remember which specific spaceship was discovered first, this was among the earliest.[1] In terms of its 64 cells, it is the smallest period 2 spaceship,[2] although there are several higher-period c/2 spaceships that are smaller.
