#C A period 264 rocket gun.
#C This rocket gun is the first in a series of rocket guns having all periods
#C of the form 264 + 8N.  It consists of ten rockets in a rectangular loop
#C defined by period 8 spark oscillators.  One corner is modified to emit an
#C output rocket every time an internal rocket passes by.
#C
#C Each rocket gun in the series is constructed in the following way.  Take
#C the newest rocket gun and remove all but one of the rockets from the loop.
#C This multiples the period by 10.  (For example, in this period 264 rocket
#C gun, the related single rocket gun has period 2640.)  Then take the right
#C half of the rocket gun, and move it to the right by 20 cells.  This adds
#C 80 to the period of the single rocket gun.  The re-populate the other nine
#C rockets into the new loop.  They will fit and still work, and the new gun
#C will have a period 8 more than the original gun.  (For example, the next
#C rocket gun in the series has period 272.)
