Reserve SR6 to n=100K, this is the sieve file. (include all remain k = 4 mod 5 for S6 and all remain k = 1 mod 5 for R6, all these k are at n=25K) (please see this file for the remain k for SR6 at n=25K which is not in CRUS)

Are you reporting your PRP´s to FactorDB?
You can also run primo to verify if its prime or composite.

Found another (probable) prime:

(101529*6^33532+1)/5

[QUOTE=MisterBitcoin;476678]Are you reporting your PRP´s to FactorDB?

Yes, I have reported all of them to FactorDB, and all of them are probable primes.

You can reserve the extended Sierpinski/Riesel conjectures, see [URL="http://www.mersennewiki.org/index.php/Sierpinski_problem_%28extended_definition%29"]http://www.mersennewiki.org/index.php/Sierpinski_problem_%28extended_definition%29[/URL] and [URL="http://www.mersennewiki.org/index.php/Riesel_problem_%28extended_definition%29"]http://www.mersennewiki.org/index.php/Riesel_problem_%28extended_definition%29[/URL] for the current status.

I use pfgw for them, and I use srsieve and sr2sieve to make the sieve file (they can only run even bases, since they cannot run the case such that both of k and b are odd).

Extended Sierpinski problem:

Finding and proving the smallest k such that (k*b^n+1)/gcd(k+1,b-1) is not prime for all integers n>=1.

Extended Riesel problem:

Finding and proving the smallest k such that (k*b^n-1)/gcd(k-1,b-1) is not prime for all integers n>=1.

All n must be >= 1.

k-values that make a full covering set with all or partial algebraic factors are excluded from the conjectures.

k-values that are a multiple of base (b) and where (k+-1)/gcd(k+-1,b-1) (+ for Sierpinski, - for Riesel) is not prime are included in the conjectures but excluded from testing.
Such k-values will have the same prime as k / b.
