#N p500 4-barrelled glider gun
#C A 4-barrelled, period 500 glider gun, based on a
#C reaction in which 2 gliders become 3.  The 2 gliders
#C hit a block, forming an R-pentomino which, catalyzed
#C by a snake, 2 blocks, a ship, and an eater, re-forms
#C the block and produces 3 gliders.  The gun contains
#C 4 copies of this reaction; 4 of the 12 output
#C gliders escape, the other 8 are reflected from
#C centinals (a p100 oscillator found by Bill Gosper)
#C to cause the reactions to repeat.
#C Built by David Buckingham about 11/17/92
