#Life 1.05
#D Sqrtgun 3.0
#D Population in generation t is asymptotic to  5 sqrt(t/12).  A 4 glider
#D salvo pushes a blinker 3 units southeast and sends back a glider,
#D which causes another salvo to be fired and a glider to be sent
#D northeast.  The round trip time, and hence the gap between
#D northeastward gliders, increases by an average of 24 generations each
#D time.  More specifically, let a[0]=207, a[1]=159, a[2]=-33, a[3]=111,
#D and a[4]=231.  For n>=0, a glider is sent northeast (by reflection from
#D a buckaroo) in generation  12 n^2 + 1116 n + a[n mod 5]  (at which
#D time, for n>=1, the population is  5n + 1297)  and escapes about 300
#D generations later.
