#Life 1.05
#D Pseudorandom LWSS generator with p46 logic
#D A lightweight spaceship stream is emitted representing a
#D pseudorandom binary sequence satisfying the recursion
#D a[n] = a[n-1] XOR a[n-19].  (By spreading out the pattern,
#D the 19 can be changed.)  The sequence has period 413385,
#D so the gun has period 46*413385 = 19015710.
