#Life 1.05
#D Sqrtgun 10.1
#D Population in generation t is asymptotic to  sqrt(5t/8).
#D A 3 glider salvo pushes a block 10 units southeast and sends back
#D 2 gliders, which cause another salvo to be fired and a glider to
#D be sent southwest.  The round trip time, and hence the gap between
#D southwestward gliders, increases by an average of 80 generations each
#D time.  More specifically, let  a[0]=a[2]=199  and  a[1]=-1.  Then, for
#D n>=0, a glider is sent southwest (by reflection from a buckaroo) in
#D generation  40 n^2 + 1120 n + a[n mod 3]  (at which time the population
#D is  5n + 1115)  and escapes about 270 generations later.
