Completed my range 100K-200K. No prime.

japelprime · 2008-03-04, 23:38

Reserving more and taking Sierp base 9 to 300k (200k-300k)

Found PRP with PRP, proven with PFGW:

8991*28^16799-1 is prime!

Don't you just love it when you can find a prime for a k within a couple hours of reserving it?

Results file is attached.

Taking Sierpinski base 11, k=958

Taking Riesel base 13, k=288

gd_barnes · 2008-03-10, 04:17

Sierp base 19 complete for all k's to n=5K. 2155 k's remaining.

Continuing to at least n=10K on all k's.

1873*30^50427-1 is prime! This is one of the lightweights, so it is good to find a prime for it.

Sierp base 19 now tested to n=7550. Since n=5K, 358 more k's were eliminated. 1797 k's now remain. All k's remaining are shown on the Sierp base 19 reservations web page. If you haven't taken a look at it, it looks kind of funny to see so many numbers on one page. lol

Continuing on to n=10K.

All base 30 k are tested to 60,000. Nothing new to report.
