With PFGW I don't really think it is worth bothering with that sort of thing. Almost all the time is spent trial factoring the candidates with large factors and prp testing them. Calculating the...

The current status of all sequences is: k=1, -1: 2, 1, 2, 1, 1, 7, 15, 35, 619, 2191, 1267, 187, 3755 >12500 k=1, +1: 1, 1, 2, 1, 5, 1, 1, 29, 3,...

I don't know how to prove that it never stops at a riesel k for starting k=1 but it is trivial to prove that some prime starting ks terminate. For k=127301 n=2 is prime and this gives k=509203 for...

I can also add 6071 after LaurV's addition on the Sierpinski list. I have tested upto n=12500 and proved all primes. I have been using a pfgw script. It...
