#Life 1.05
#D Pseudorandom number generator with p120 logic
#D A glider stream is emitted representing a pseudorandom binary
#D sequence satisfying the recursion  a[n] = a[n-1] XOR a[n-11].
#D (By spreading out the pattern, the 11 can be changed.)  The
#D sequence has period 1533, so the gun has period 120*1533 = 183960.
