The trouble with certifying with Primo is that it takes several months and there is no coordination so that people are not stepping on each other's toes. This happened with Peter Kaiser and me with a 29k proof of a Lucas number. As it happened, I took Peter's partially finished work and ran it on my faster computer and we shared the credit. Perhaps a Primo reservation thread might be in order!

The 331st fullyfactored or probablyfullyfactored Mersenne number with prime exponent (not including the Mersenne primes themselves) is M15359.
The latest factor was found by Niels Mache Nextcloud, and the PRP test on Primenet was done by Anonymous. FactorDB link

This is a semiprime. The 56digit factor was found by Ryan Propper, and the PRP test on Primenet was done by ATH. FactorDB link
