Default Where do I send my PRP primes with large k?

3*5*11*13*98584369*2^25615- 1 is 3-PRP! (5.6118s+ 0.0005s)
3*5*11*13*98584369*2^25970- 1 is 3-PRP! (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.

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 25970

Hi Ed,

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*2^25615-1 [N+1, Brillhart-Lehmer-Selfridge]
Running N+1 test using discriminant 7, base 1+sqrt(7)
Calling Brillhart-Lehmer-Selfridge with factored part 99.86%
3*5*11*13*98584369*2^25615-1 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
