On 12 December, 05:32:25 UTC, PrimeGrid’s Generalized Fermat Prime Search found the Generalized Fermat mega prime:

6287774^262144+1

The prime is 1,782,186 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 10th for Generalized Fermat primes and 66th overall.

The discovery was made by Greg Miller (Olgar) of the United States using an NVIDIA GeForce GTX 1050 in an AMD Phenom(TM) II x4 965 CPU with 16GB RAM, running Windows 10 Professional Edition. This GPU took about 60 minutes to probable prime (PRP) test with GeneferOCL2. Greg is a member of the USA team.

The PRP was confirmed prime by an Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz with 16GB RAM, running Microsoft Windows 10 Professional. This computer took about 15 hours 44 minutes to complete the primality test using LLR.

For more details, please see the official announcement.

The big number on the left side of the front page is missing a 7, saying 628774 instead of 6287774. That would make the number only 1,520,041 digits long.
