#N Sqrtgun 10.1
#O Dean Hickerson, drhickerson@ucdavis.edu 2/14/91
#C Population in generation t is asymptotic to sqrt(5t/8)
#C A 3 glider salvo pushes a block 10 units southeast and
#C sends back 2 gliders, which cause another salvo to be
#C fired and a glider to be sent southwest. The round
#C trip time, and hence the gap between southwestward
#C gliders, increases by an average of 80 generations
#C each time. More specifically, let a[0]=a[2]=199 and
#C a[1]=-1. Then, for n>=0, a glider is sent southwest
#C (by reflection from a buckaroo) in generation
#C 40 n^2 + 1120 n + a[n mod 3] (at which time the
#C population is 5n + 1115) and escapes about 270
#C generations later.
