Curious: the 5 digits of the k-value appear also in the n-value.
Awaiting official announcement, still some tasks open for this k. |
Congratulations!
This is the 97th prime with between 2 million and 3 million digits.
There are 10 primes in total (in that range) of the form k* 5^n +/- 1. (8 with -1 and 2 with +1)
