A period 10860 c/5 spaceship.
This spaceship turns a pair of gliders into a stable configuration of
three blocks and a ship.  The configuration is then later perturbed into
another pair of gliders which are turned back to complete the loop.
By varying the position of the components, arbitrarily large period
spaceships can be constructed without increasing the population.
David I. Bell, February 1999
