Threads that are inactive for more than 2 weeks will be locked. If you want a thread opened PM me. This will help reduce the clutter.
Try to keep your project limited to 12 threads. Last fiddled with by Citrix on 20071217 at 12:48

I know we have 45 threads for the effort but it's potentially so large that I think we'll need them. Also Xyzzy indicated that we may get our own project forum at some point. Thanks, Gary

You can now lock the Sierpinski bases 6 thru 18, base 10, base 22, and base 23 threads whenever you think it is appropriate. About the "even k's and the Sierprinski and Riesel conjectures" threads. We'd want to keep those open for now. At the current time, I am not including any multiples of the bases in the conjectures searches. But within the next month, I plan to create a separate page just for k's that are multiples of the base but have a different lowest first primes for n>=1, i.e. 45*10^n1 has a prime at n=1, but 450*10^n1 doesn't have a prime until n=11958; so that is one that would be shown. k=4500 would not be shown because it has the same lowest prime as k=450. The same thing for 22*22^n+1, which has no prime at all, although 1*22^n+1 is prime for n=1. The even k's and the Sierpinski and Riesel conjectures threads will fit right in with the 'multiples of the base' effort. If those aren't 'official prime search projects', I'll check with the folks in those threads and see if they are OK with including them in this effort.

The "I Hate n=333,333" Project
Would anyone like to help me start an "I hate n=333,333" Project? Basically, the goal of this project is to find and prove primes bigger than about 100,365 digits, and submit them to Prime Pages. There is something very annoying to me about how boring the bottom of the top5000 list looks.
Basically, we'd pick an nvalue slightly above n=333,333, and try to knock all the n=333,333 primes off the list as quickly as possible. Anybody interested?

I don't agree with fixedn searches unless all kvalues with primes are 'filled in' up to the nvalue of the prime afterwords. Look for something big from me in less than 2 weeks that is not fixedn but that will help with this. You'll know it when you see it. Gary

You should think this thru so that you don't end up repeating history.

Yeah, I thought about commenting on this, I guess I should have gone with my gut. Basically, I'm thinking we would pick a small range, something that amounts to a year or two of LLR on one core when it's sieved to a sufficient depth. When that's done, simply move on to another number.

Jasong, You HAVE your wish!! Now announcing the 'No Prime Left Behind' project. Time to take out many of those n=333333 primes in rapid succession and make the bottom of the top5000 list look good again! Come join us here. Gary

I would like to write code for something that would do something significant within a year. Any ideas? I thought maybe solving mancala with several different rule sets? Only one has been done.
