On 17 June 2018, 15:40:35 UTC, PrimeGrid’s Generalized Fermat Prime Search found the Generalized Fermat mega prime:

5205422^262144+1

The prime is 1,760,679 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 8th for Generalized Fermat primes and 60th overall.

The discovery was made by Scott Brown (Scott Brown) of the United States using an NVidia GeForce GTX 1080 in an Intel(R) Xeon(R) E5-1650 v3 CPU @ 3.50GHz with 32GB RAM, running Windows 7 Enterprise Edition. This GPU took about 18 minutes to probable prime (PRP) test with GeneferOCL3. Scott is a member of the Aggie The Pew team.

The prime was verified on 17 June 2018, 16:44:04 UTC by Keith Reinhardt (Keith) of Canada using an NVidia GeForce GTX 1050 Ti in an Intel(R) Core(TM) i7-4790 CPU at 3.60GHz with 16GB RAM, running Windows 7 Professional Edition. This GPU took about 43 minutes to probable prime (PRP) test with GeneferOCL5. Keith is a member of the BOINC@Denmark team.

The PRP was confirmed prime by an Intel(R) Xeon(R) E3-1240 v6 CPU @ 3.70GHz with 2GB RAM, running Linux. This computer took about 5 hours 50 minutes to complete the primality test using multithreaded LLR.
