This is for the Penta-Fibonacci sequence

We try up to the , 250000, terms, those for which it is does not suffice to f\
    ind a period are labeled FAIL



    The first, 30, terms of the Pisano periods mod m, starting with m=1 are

[1, 6, 104, 12, 781, 312, 2801, 24, 312, 4686, 16105, 312, 30941, 16806, 81224,
