On 12 August 2024, 01:42:48 UTC, PrimeGrid's Primorial Prime Search found the Primorial Prime:

6354977#-1

The prime is 2,758,832 digits long and will enter “The Largest Known Primes Database” ranked 2nd for Primorial primes and 157th overall.

The discovery was made by Tom Greer (tng) of the United States using an AMD Ryzen 9 9950X @ 4.30GHz with 32GB RAM, running Microsoft Windows 10 Professional x64 Edition. This computer took about 4 hours, 24 minutes to complete the probable prime (PRP) test using PRST with 4 threads. Tom Greer is a member of Antarctic Crunchers.

The PRP was confirmed prime on 17 August 2024 by an AMD Ryzen 9 7950X3D @ 4.20GHz with 128GB RAM, running Debian 12.5. This computer took about 5 days, 6 hours, 49 minutes to complete the primality test using PFGW with 4 threads.
