Considering the link, I'd say no. Most definitely not literally.
I just hope there's a log of what this guy set prime...

Realistically, I can't imagine anybody having a need to set a number prime. (Well, maybe one or two people here.) So if there is a log, it's all his...

On a brighter note, let it be known that Syd [URL="http://homepage2.nifty.com/m_kamada/math/c/60001.htm#N242_C243"]had factored[/URL] [URL="http://factordb.com/search.php?query=6*10%5E242%2B1"]6*10^242+1[/URL]

I think the only times I've used it are on easy PRPs (under about 200 digits) taking a bit longer to verify than I'd like (yes, I checked it first), and on large numbers (over about 1000 digits) where the DB had it as Unknown and I knew it was PRP or prime.

I did use it a couple of times on 3-4K digit primes which I certified with Primo.

816k numbers in the work queue, number quickly dropping - I guess Syd might have queued all primes for a re-check to sort out the fals ones?

lets hope this isnt a measure of how many false primes it finds and then tries basic factoring techiniques on:smile:

Pascal's Odd Perfect Number search has many factors for p^q-1 that are not yet in Brent's tables nor the database. Of course even more of these factors are already in both repositories. I've manually added about a dozen missing factors to the database in the last few days, but it's tedious. Is there a way to scoop these all up and find the new factors?

R. Gerbicz has pointed out there is a least one factor in the database that is not in Pascal's list nor Brent's table. I haven't found any others in my manual comparison process, but that is also tedious. Are these factors automatically submitted to Richard Brent? Richard has not updated his factors table (for a^n +/- 1 with both a and n < 10,000) since September, so they might be "in process." Even if Richard gets the factors, Pascal wouldn't find any database factors for bases > 10,000. Is there some way to automatically get all new "factors of interest" for Pascal - or perhaps all the known factors and let Pascal figure out which are new?
