#Life 1.05
#D p500 4-barrelled glider gun
#D A 4-barrelled, period 500 glider gun, based on a reaction in which
#D 2 gliders become 3.  The 2 gliders hit a block, forming an
#D R-pentomino which, catalyzed by a snake, 2 blocks, a ship, and an
#D eater, re-forms the block and produces 3 gliders.  The gun contains
#D 4 copies of this reaction; 4 of the 12 output gliders escape, the
#D other 8 are reflected from centinals (a p100 oscillator found by
#D Bill Gosper) to cause the reactions to repeat.
