Pseudorandom number generator with p120 logic A glider stream is emitted representing a pseudorandom binary sequence satisfying the recursion a[n] = a[n-1] XOR a[n-11]. (By spreading out the pattern, the 11 can be changed.) The sequence has period 1533, so the gun has period 120*1533 = 183960. Dean Hickerson, dean@ucdmath.ucdavis.edu 3/21/92
