#N Sqrtgun 3.0
#O Dean Hickerson, [e-mail]  1/28/91
#C Population in generation t is asymptotic to
#C 5 sqrt(t/12).  A 4 glider salvo pushes a blinker 3
#C units southeast and sends back a glider, which causes
#C another salvo to be fired and a glider to be sent
#C northeast.  The round trip time, and hence the gap
#C between northeastward gliders, increases by an average
#C of 24 generations each time.  More specifically, let
#C a[0]=207, a[1]=159, a[2]=-33, a[3]=111, and a[4]=231.
#C For n>=0, a glider is sent northeast (by reflection
#C from a buckaroo) in generation
#C 12 n^2 + 1116 n + a[n mod 5]  (at which time, for
#C n>=1, the population is  5n + 1297)  and escapes about
#C 300 generations later.
