59*2^3408416-1 (1026038 digits) so far it's the smallest known megaprime :whistle:
Verification using PFGW:[code]Primality testing 59*2^3408416-1 [N-1/N+1, Brillhart-Lehmer-Selfridge]
Running N-1 test using base 3
Running N+1 test using discriminant 7, base 6+sqrt(7)
Running N+1 test using discriminant 7, base 10+sqrt(7)
Special modular reduction using FFT length 224K on 59*2^3408416-1
Calling N+1 BLS with factored part 100.00% and helper 0.00% (300.00% proof)
59*2^3408416-1 is prime! (110852.6366s+0.0192s)[/code]
