Congratulations Dr. Ryan.

One down for the Riesel-base 5 conjecture:

[url='https://primes.utm.edu/primes/page.php?id=134054']64598 * 5^3769854-1[/url] is prime, 2,635,020 digits, found on 2022-06-14 by PrimeGrid.

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)

Even more curious: The digits 3 through 9 all occur 1 time in the n-value.

And there is new one :)
