Great find, congratulations.
I am updating some related entries in OEIS.
The prime must be added to the database so that it will appear here: https://www.primegrid.com/primes/primes.php?project=PRS And also can be unhidden here: http://prpnet.primegrid.com:12008/user_primes.html
Top Twenty: Primorial. Note that only three entries have been found in the last twenty years, all by PrimeGrid.

It has been proven as prime. Congratulations on such a rare find.
It has been more than 20 years since the last +1 primorial has been found. Maybe PrimeGrid can find one of those in the near future as well.
IMO although this is just a mega prime and wasn't found via BOINC, I think it requires a news entry on the main page due to the rarity for primes of that form. |

That definitely is going to happen. (It was planned all along.)

Yes, during all these years, no primorial of the c=+1 type found.
The last one found (before the era of PrimeGrid) has under 170'000 digits and fell off the regular Top 5000 on 29 October 2010.
By the way, from 16 March 2021 until Aeneas's find there were no primorials of any type on the Top 5000 proper since 1098133#-1 of user jpaul, team Aggie The Pew, fell off the list.
