#N Sawtooth with external timing
#O David I. Bell, dbell@pdact.pd.necisa.oz.au, 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.
