I split up the factors file into 6 and had 5 cores going ahead.
Only recently did I restart the 6th core.
The Prime was in the 6th, so I ended up doing twice as much testing as I had to.
Feeling very happy about it! :smile:
Base released.

SR5 rank 73 in Top 5000

Looks like I've found BIG prime today. N+1 test in progress, stay tuned.

It's happened several times on this project: When big primes come, they come in triplet. Yours would be the 3rd over the last several days.

The most unbelievable thing that new prime was found by the same machine and exact the same core which found previous big prime (22*900^252407-1) one week ago!

Is this in the right thread? That doesn't appear to be found as part of this project.

Congrats nonetheless.
