But for now I'll see when I can continue do more work on Riesel base 3, on my own... maybe in a month or a couple of years, who knows what I decide once I complete the work I've left as reserved... KEP

Carlos,
I think Micha indicated an interest in sieving Riesel base 3 k<100M for n=25K100K. If he's working on that, I'll create a minidrive out of that base when he's done sieving to n=~100G or so. If he's not working on it, I'll start some sieving on it next week. Gary Last fiddled with by gd_barnes on 20081005 at 03:04 Reason: Correct sieving limit

KEP reported by Email that he has completed Riesel base 3 up to k=250M and n=25K on Oct. 1st!
The effort was reviewed and is correct. Very nice work! There are now 1178 k's remaining for k<250M. The web pages have now been updated for all reservations, search ranges, and primes at CRUS in the last week. Gary

Micha confirmed by PM that he is sieving Riesel base 3 for k<100M and n=25K100K. After he has sieved to an appropriate depth, I'll start a minidrive for n=25K50K.

Feel free to take the next 23 of them or grab a file from the Sierp minidrive. n=1K files posted are now posted there for n=85K100K. Gary

I would like to reserve k<=5M up to 1M for Riesel base 3. I'm still keeping my other reservations, but I feels like I wanna be part of finding bigger primes. Already now it appears to be rather easy sieveable, so I'll sieve the 3 k's untill my Sierp base 19 reservation is completed and then I'll pause any else I've pending and work on this recent Riesel base 3 reservation
Hope its ok KEP EDIT: Just for clearence, I'm keeping all currently reserved work, but would like to add this to my list of reservations Last fiddled with by KEP on 20081005 at 14:13

OK, that's fine. As prime as base 3 is, I would expect you to find a prime on all of them before n=1M. Good luck on finding a top5000 prime! Gary Last fiddled with by gd_barnes on 20081006 at 08:28

At 151,700,000,000 p ~43,331 candidates remain. If a top5000 candidate exists I'll catch it, no doubt about it Kenneth!

VERY nice! 91222 digits. Not far from top5000 territory. Historical note: This is the 6th largest prime ever found for Riesel base 3!! k=3677878 is now the lowest k with no prime for this base. Last fiddled with by gd_barnes on 20081013 at 22:21
