Re: [PrimeNumbers] PRP Top 50 has become PRP Top 100
- Hi Mike,
There is an error in the value of n = 4497, the value should be n = 44497.
Thanks for the quick response.

Something must be wrong with your expression as (if we do the substitutions
for n and k) PFGW says:-
6*8939*(2^4497-1-8939)+2^4497-1 has factors: 7
Want to double-check it?
