On 24 September 2022, 15:01:43 UTC, PrimeGrid's Generalized Fermat Prime Search found the Mega Prime:

1963736^1048576+1

The prime is 6,598,776 digits long and will enter Chris Caldwell's “The Largest Known Primes Database” ranked 1st for Generalized Fermat primes and 13th overall.

The discovery was made by Tom Greer (tng) of the United States using GeneferOCL5. Tom Greer is a member of the Antarctic Crunchers team.

The prime was verified by Wolfgang Schwieger (DeleteNull) of Germany using GeneferOCL5. Wolfgang Schwieger is a member of the SETI.Germany team.

The PRP was confirmed prime on 26 September 2022 by an AMD Ryzen 9 5950X @ 3.4GHz, running Linux Mint. This computer took about 51 hours, 40 minutes to complete the primality test using LLR2.

For more details, please see the official announcement.
