PFGW:
Primality testing (7*10^(2*13977+1)-27*10^13977-7)/9 [N-1/N+1, Brillhart-Lehmer-Selfridge]
Running N-1 test using base 5
Running N+1 test using discriminant 11, base 1+sqrt(11)
Calling N+1 BLS with factored part 0.13% and helper 0.01% (0.40% proof)
(7*10^(2*13977+1)-27*10^13977-7)/9 is Fermat and Lucas PRP!
