#D Orthogonal sawtooth with expansion factor 21
|
|
#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 generation t = 18*21^n + 222 (n>=0), is
|
|
#D 7t/60 + 1290, but the population in generation 6*21^n + 193 (n>=1)
|
|
#D is only 1212.
|
|
#D This uses a spark from a c/3 orthogonal spaceship ("turtle") to turn
|
|
#D a HWSS into a loaf, which is then pulled back by pairs of LWSSs. When
|
|
#D the loaf is pulled all the way back, another HWSS is fired toward the
|
|
#D c/3, starting the cycle again. The HWSS synthesis, using 2 gliders,
|
|
#D a Kok's galaxy, and a figure 8, is due to David Buckingham.
|
|
#D This was the first sawtooth built.
