On 22 March 2017, 09:33:58 UTC, PrimeGrid’s Generalized Fermat Prime Search found the Generalized Fermat mega prime:

2676404^262144+1

The prime is 1,684,945 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 5th for Generalized Fermat primes and 52nd overall.

The discovery was made by Wolfgang Schwieger (DeleteNull) of Germany using an NVIDIA GeForce GTX 1070 in an Intel(R) Core(TM) i7-6700K CPU at 4.00GHz with 16GB RAM, running Linux. This GPU took about 16 minutes to probable prime (PRP) test with GeneferOCL4. Wolfgang is a member of the SETI.Germany team.

The prime was verified on 22 March 2017, 23:16:34 UTC by William de Thomas (wdethomas) of Puerto Rico using an NVIDIA GeForce GTX Titan X in an Intel(R) Core(TM) i7-4790K CPU at 4.00GHz with 16GB RAM, running Microsoft Windows 10 Professional Edition. This GPU took about 18 minutes to probable prime (PRP) test with GeneferOCL4. William is a member of the Puerto Rico Assisting Science 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 8 hours 40 minutes to complete the primality test using LLR.
