#D Stable reflectors.
#D 
#D At the top are some stable reflectors for the simple 6-cell spaceship.
#D The first one is large, but it has the advantage that it works for periods as low as 5,
#D whereas the second 90-degree one requires the period to be at least 21,
#D the third requires at least 22, the fourth at least 13 and the fifth at least 19.
#D 
#D Along the middle are shown the first three of an infinite sequence of stable
#D 180-degree reflectors for larger spaceships.
#D 
#D Another reflector for a large spaceship is at bottom left.
#D 
#D A reflector for a p6 spaceship is shown at bottom right.  This reflector works for all
#D phases of the spaceship - the timing shown here is the one that produces no
#D phase shift.
