117690*31^108349-1 is prime.

Nice one Chris.

Let's hope this is the start of another nice run.

8579*10^373260-1 (373264 digits) it took me 18 hours to verify

Great find! This is the third largest prime found by this project. Don't forget to submit it to the Prime Pages.

Thanks! I've already done that, see here. I don't know why it doesn't appear on the status page...

Probably because it hasn't been verified yet.

According to the "**info" link shown in the picture:

The fact that The Prime Pages allowed unmoderated submissions, attracted a variety of vandals. To minimize the damage these unstable folks cause, we have implemented a variety of moderation methods. For example, primes from new proof-codes (those with no proven primes) will not show until they are verified. Also, the smaller primes with comments will not appear until both the numbers and the comment are both fully verified. Even after these numbers and comments are verified, it may still be another hour until the primes show, because the system must update the database first. If you notice any troubles with these new measures, please let me know: caldwell@utm.edu.

I think this is Cruelty's first prime for this prover-code, so that would explain it.

Awesome find Cruelty! Congrats! Bring on the dancing Georges:

I think we need to concentrate all of our efforts on the 350000-380000 digit area. :-) That's 4 huge primes in that range out of 33 current top-5000 primes for the project!

Excellent, great proof Serge!

Whew, those powers-of-2 k's on the low-conjecuted Sierp bases are TOUGH to find a prime for. But when we do, they're huge!

At 270K+ digits, this deserves a couple of dancing georges...

You having fun yet?

23*110^78120-1 is prime!

Last k eliminated.

Results attached.
