Primality testing phi(32481,10) [N-1/N+1, Brillhart-Lehmer-Selfridge]

Running N-1 test using base 43

Running N-1 test using base 59

Running N+1 test using discriminant 67, base 14+sqrt(67)

Calling N-1 BLS with factored part 1.37% and helper 0.06% (4.17% proof)

phi(32481,10) is Fermat and Lucas PRP! (173.0450s+0.0062s)
