#Life 1.05
#D Orthogonal sawtooth with expansion factor 6
#D Population is unbounded but does not tend to infinity.  Its graph is
#D a sawtooth function with ever-increasing teeth.  More specifically,
#D the population in generations  t  near  28*6^n  is about  t/5  if
#D t  is odd and about  3t/20  if  t  is even, but the population in
#D generation  14*6^n - 84  (n>=2)  is only 562.  (Even more
#D specifically, the population in generation  t = 28*6^n + 12  (n>=1),
#D is 3t/20 + 555  and it drops to  t/5 + 599  in the next generation.)
#D 
#D This uses a spark from a period 4, speed c/4 orthogonal spaceship,
#D found by Tim Coe, to turn one LWSS into a loaf, which is then pulled
#D back by subsequent pairs of LWSSs. When the loaf is pulled all the
#D way back, it gets deleted and the cycle begins again.
