Riesel Primes k*2^n-1, k<300 [Part II] - Page 4

Nuggetprime informed me that he doesn't have enough resources to continue his search of k=139 right now but he hopes he will be able to resume his search later this year.

I'll leave k=139 reserved for him for a while but if somebody wants to test it we can cancel his reservation.

Carlos decided to release k=33 for the time being.

k=19 has been tested to 1M. There are no new primes, but I'm continuing with it.

The last time I posted residues was at 940K, so the attachment contains residues from 940K-1M.

Kosmaj, are you still working on k=83? If yes then this looks like something personal...

arminius · 2007-08-16, 18:00

Update:
LLR complete to 950k.
No new primes.

amphoria · 2007-08-18, 18:51

LLR at n=900k.

No new primes since last update.

MooooMoo · 2007-08-22, 21:27

Please note that the search limits for k=19, 49, and 81 have not been updated on http://www.15k.org/riesellist.htm , even though the page says that it has been updated on August 20th.

VBCurtis · 2007-08-24, 07:04

13 and 127 have hit 1.1M on LLR.
reserving 119 from 500k to 1M.

k=251 tested to 700,000. Continuing.

Cruelty · 2007-09-03, 07:52

k=141,151,199,269 done till n=600000.
"Only" 5 primes for k=199 found in this range

I am releasing k=199, and continue testing 141,151 and 269 until I find a prime for each of these

Kosmaj · 2007-09-04, 04:55

Okay, I updated the stats page accordingly (The first update after more than 10 days because the ftp server was down.)

k=199 is now up for grabs!

I'm afraid that for at least one of your remaining k's you will have to go into mega-bit exponents to find the next prime. But I know that's not a problem for you.
