Trial divisions to 10^14

Primality testing (531^131072+25^131072)/2 [N-1/N+1, Brillhart-Lehmer-Selfridge]
Running N-1 test using base 3
Running N+1 test using discriminant 7, base 1+sqrt(7)
Calling N-1 BLS with factored part 0.01% and helper 0.00% (0.02% proof)
(531^131072+25^131072)/2 is Fermat and Lucas PRP! (6948.8084s+0.0126s)
