How to use LLR?
Can someone help me? I want to use LLR to find the smallest (probable) prime of the form (185^n1)/184 (base 185 repunit, I already know that this is composite for all n<=60000, and this can be prime only for prime n), thus I download the program cllr.exe, and I type this in the sieve file:
Code:
ABC (185^$a1)/184 a: primes from 60000 to 100000 Code:
Invalid ABC format, next data lines will be flushed...

So if I want to use LLR to test all numbers of the form (b^n1)/(b1) with b=185, 269, 281 and 60000<=n<=100000 with prime n, what should I type?

Why bother? PFGW is much better at this sort of thing. More from the documentation: Quote:

The great advantage of pfgw over LLR is that pfgw test any form while LLR is limited to some form. But multithreading on LLR is faster than on the new version of pfgw64 with the T switch. I don't know if I don't know how to use the T switch on pfgw.
