#C This is a "moving" sawtooth pattern constructed of two period 90 c/3 rakes,
#C a period 8 c/2 blinker puffer, and three period 3 edge-repair spaceships.
#C This sawtooth has an expansion factor of three.  This sawtooth is an  
#C improvement on a previous one.
#C 
#C The blinker puffer lays down a trail of blinkers.  Meanwhile the two c/3
#C rakes produce pairs of backwards gliders which normally destroy each other.
#C But eventually a pair of the gliders hits the end of the trail of blinkers.
#C This ignites the blinker trail and creates a block and a glider.  The block
#C and glider are deleted by period 3 edge-repair spaceships.  The blinker
#C trail burns up completely, completing the cycle.  But in each cycle, the
#C c/2 blinker puffer moves further ahead of the c/3 rakes, so the blinker
#C trail becomes longer in a geometric progression.
#C 
#C Removing the single or the pair of edge-repair spaceships at the back
#C results in a pattern which grows in a logarithmic manner where a glider
#C of block is emitted at increasing intervals.
