#N Sawtooth with external timing
#O David I. Bell, [e-mail], 27/10/92
#C A p8 blinker puffer (found by Bob Wainwright) moves
#C west.  A glider bounces between a fixed reflector (in
#C gens  480*2^n-701  (n>=1)) and a southeastward
#C Cordership (in gens  720*2^n-661  (n>=1)).  Each
#C bounce from the fixed reflector releases a salvo
#C (formed in gens  480*2^n-310  (n>=1)) consisting of a
#C MWSS and 2 LWSSs aimed toward the line of blinkers.
#C The salvo hits the nearest blinker in gen
#C 2400*2^n-880n-3115  (n>=1), causing the blinker line
#C to decay at 2c/3.  (Another salvo, present in the
#C initial pattern, hits in gen 5.)  When the decay
#C catches up to the puffer, a new line of blinkers
#C starts to form (in gen 3840*2^n-880n-3760  (n>=0)).
#C
#C When the salvo hits the blinker line, the population
#C is large, about  180*2^n  in gens around  2400*2^n.
#C (Specifically, in gen 2400*2^n-880n-3115  there are
#C 60*2^n-29  blinkers.)  When the decay catches up with
#C the puffer, the population is bounded, about 1400 in
#C gens around  3840*2^n-880n.
