I plugin following numbers: Code: 104 2 -1 500000 3 5 13 Checking k*2^n-1 sequence for exponent=104, bound for primes in the covering set =500000, bound for k is 3 Examining primes in the covering set: 3,5,17,8191,2731,53,157,1613 And their orders: 2,4,8,13,26,52,52,52 Base = 104 2 = exponent -1 = Riesel 500000 = k ?? ?? Thank you!
