64P2H1V0 is an unnamed orthogonal c/2 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. In terms of its 64 cells, it is the smallest period 2 spaceship, although there are several higher-period c/2 spaceships that are smaller.
