Looks like there are two top-5000 primes yet to report from 6 days ago. One from Max and one from Sashixi.

Interestingly there were 3 primes found within 2 hours of each other on Feb. 27th; by 3 different people.

It turns out that the "prime" 455*2^1560160-1 that Sashixi found was not prime.

After not being able to get a hold of him, I submitted it to the top-5000 site and it came back as composite. In the future, I will doublecheck any prime that this user finds.

Dave, can you remove this "prime" from the database? Thanks.

That would be a good feature for the prpnet server to automatically check primes. It is probably the same issue that used to give me some false primes and others for GIMPS. It took a bios update for my pc to become stable.

Hi Gary. It took me a couple of days to catch this message.
Will do, tomorrow night, after I get home.
