#N Sawtooth with external timing
#C (The comments below are for an earlier version of this pattern.  The
#C generation numbers are no longer correct.)
#C
#C A p8 blinker puffer (found by Bob Wainwright) moves west.  A glider
#C bounces between a fixed reflector (in gens  480*2^n-701  (n>=1))
#C and a southeastward Cordership (in gens  720*2^n-661  (n>=1)).
#C Each bounce from the fixed reflector releases a salvo (formed in
#C gens  480*2^n-310  (n>=1)) consisting of a MWSS and 2 LWSSs aimed
#C toward the line of blinkers.  The salvo hits the nearest blinker
#C in gen  2400*2^n-880n-3115  (n>=1), causing the blinker line to
#C decay at 2c/3.  (Another salvo, present in the initial pattern,
#C hits in gen 5.)  When the decay catches up to the puffer, a new
#C line of blinkers starts to form (in gen 3840*2^n-880n-3760  (n>=0)).
#C
#C When the salvo hits the blinker line, the population is large,
#C about  180*2^n  in gens around  2400*2^n.  (Specifically, in gen
#C 2400*2^n-880n-3115  there are  60*2^n-29  blinkers.)  When the
#C decay catches up with the puffer, the population is bounded, about
#C 1400 in gens around  3840*2^n-880n.
