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