Where do I send my PRP primes with large k?
3*5*11*13*98584369*2^25615 1 is 3PRP! (5.6118s+ 0.0005s)
3*5*11*13*98584369*2^25970 1 is 3PRP! (5.7561s+ 0.0006s) Where would I send these along with other primes to prove they are primes? I can't use proth and llr they won't accept it. (Yes I know my computer is slow)

LLR can prove primality of your PRPs. Just replace k with its numerical value (instead of product of its factors) and attach the right header:
1000:M:1:2:2 211463471505 25615 211463471505 25970

if you stick to PFGW, you can test the primality using the "tp" switch, e.g.: Code:
pfgw tp inputfile.txt Code:
Primality testing 3*5*11*13*98584369*2^256151 [N+1, BrillhartLehmerSelfridge] Running N+1 test using discriminant 7, base 1+sqrt(7) Calling BrillhartLehmerSelfridge with factored part 99.86% 3*5*11*13*98584369*2^256151 is prime! (2.5064s+0.0001s)

Ok, I tried that and it works, before it crashed when I tried LLR with the file directly outputted from newpgen
