 2008-11-21, 23:06 #243 Happy5214     "Alexander" Nov 2008 The Alamo City 349 Posts k=37 Hi, I'm Happy5214. I don't know if Kosmaj mentioned this to you, but back in March, I reserved k=37 n>800K. I have finally started work on it. It will be hosted on my personal forums at my website. The sieve post will be added to that forum. Website: happy5214.no-ip.org Work: Sieving n=800-900K Thanks -Happy5214
 2008-11-22, 08:56 #244 Kosmaj     Nov 2003 2×1,811 Posts Happy, k=37 is already tested to 1M. Let me know if you want to pursue higher ranges or switch to another k.
 2008-11-22, 15:27 #245 Happy5214     "Alexander" Nov 2008 The Alamo City 15D16 Posts It would have been nice to know that before I did all that sieving. Yeah, I will pursue higher ranges. Sieving 1-1.5M. -Happy5214
 2008-12-03, 22:44 #246 VBCurtis     "Curtis" Feb 2005 Riverside, CA 19·223 Posts Updates on the k's sieved by Cruelty and handed down to me: 109 800k 131 735k 141 800k 221 860k 281 735k Steven has taken over testing k=221 from me- like Cruelty, I plan to find a prime for each k and then hand it off to someone else. Buzzodan searched these k's in 765-800k range, and is continuing to assist with some of the k's above 800,000. I am actively searching 131 and 281 (and 211, which he also did on 765-800) to close the gap to his completed range. Once again, thanks to Cruelty for providing a file sieved to 50T. -Curtis

 2008-12-15, 22:31 #249 Happy5214     "Alexander" Nov 2008 The Alamo City 5358 Posts k=37, 19 Hi, it's me. k=37 tested to n=1011K, no primes found. Reserving k=19, will start when k=37 catches up to n=1206K. Thomas, it says on the stat page that k=29 has been released. Excuse me if I missed something earlier, but did you actually release that? -Alexander Jones
 2008-12-24, 22:11 #250 VBCurtis     "Curtis" Feb 2005 Riverside, CA 19×223 Posts 415 complete to 555k. Prime found at 548359, reported Monday by Gary. Alas, I was on vacation and unable to report it myself. I am continuing with this k after a sizable break- the machine running it died, and it took me quite a few months to recover the data from it (including sieves for 405 and 415). Work on 405 will continue from 600k after some more sieving. -Curtis

 2009-01-10, 09:50 #253 VBCurtis     "Curtis" Feb 2005 Riverside, CA 108D16 Posts I have many gaps to fill in the next few weeks, but here are some up to date ranges: 13 complete to 1.8M (was 1.6M). 43 complete to 1325k (was 1000k) 127 complete to 2.0M (was 1.85M) -Curtis
