On 3 April 2018, 15:55:55 UTC, PrimeGrid’s Extended Sierpinski Problem Prime Search project found the Mega Prime:
193997*2^11452891+1
The prime is 3,447,670 digits long and will enter Chris Caldwell's The Largest Known Primes Database ranked 23th overall. This find eliminates k=193997; 10 k's remain in the Extended Sierpinski Problem.
The discovery was made by Tom Greer (tng*) of the United States using an Intel(R) Xeon(R) E5-2620 v3 CPU @ 2.40GHz with 16GB RAM, running Microsoft Windows 10. This computer took about 3 hours 45 minutes to complete the primality test using multithreaded LLR. Tom is a member of the Sicituradastra. team.
The prime was verified on 4 April 2018, 00:17:20 UTC by Gary Bauer (GDB) of the United States using an Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz with 16GB RAM, running Microsoft Windows 10. This computer took about 2 hours 25 minutes to complete the primality test using multithreaded LLR.
For more details, please see the official announcement. | |

That is wrong. There were four megaprimes just recently, actually.
Don't forget that since the beginning of the year, the criteria for a newspost about a prime have been changed, resulting in less frequent posts. The primes are still found. | |

Oh. Have we finished? I'll go back to SETI then. Hope it's not a Tuesday.

By a large margin we're finding more mega primes this year than ever before. We found 4 mega primes in one day earlier this week. 47 have been found so far this year, and it's still May. The record for a full year is 61.
What's different is we're no longer doing the big flashy announcements for all mega primes. The bar has been raised and only primes that make it into the top 100 known primes get announcements. People were complaining that there were too many announcements. It was getting routine and tedious, for us as well as them.
In 2018, therefore, we have lots more mega primes and a lot fewer announcements.
