#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.
