k=139

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 [URL="http://primes.utm.edu/primes/page.php?id=81948"]this[/URL] looks like something personal...

k=49

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

 amphoria 2007-08-18 18:51

k=81

LLR at n=900k.

No new primes since last update.

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

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

k=251

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

 Kosmaj 2007-09-04 04:55

Okay, I updated [URL="http://www.15k.org/riesellist.htm"]the stats page[/URL] 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. :smile:
