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