An inefficient but amusing period 874 = 46*19 glider gun based on
a 3 glider collision that produces 4 blocks, 4 beehives,
8 blinkers, and 13 gliders. 28 p46 shuttles are used to redirect
some of the gliders: 1 escapes, 1 is destroyed, 8 are reflected
back to delete the debris, and 3 are reflected back to collide
again.
