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