- #N Orthogonal sawtooth with expansion factor 6
- #O Dean Hickerson, drhickerson@ucdavis.edu 8/14/92
- #C Population is unbounded but does not tend to infinity.
- #C Its graph is a sawtooth function with ever-increasing
- #C teeth. More specifically, the population in
- #C generations t near 28*6^n is about t/5 if t is
- #C odd and about 3t/20 if t is even, but the
- #C population in generation 14*6^n - 84 (n>=2) is only
- #C 610. (Even more specifically, the population in
- #C generation t = 28*6^n + 12 (n>=1), is 3t/20 + 603
- #C and it drops to t/5 + 647 in the next generation.)
- #C
- #C This uses a spark from a period 4, speed c/4
- #C orthogonal spaceship, found by Hartmut Holzwart, to
- #C turn 2+1/2 pairs of LWSSs into a loaf, which is then
- #C pulled back by subsequent pairs of LWSSs. When the
- #C loaf is pulled all the way back, it gets deleted and
- #C the cycle begins again.
