I'm willing to sieve it a little deeper if it goes that high, for future public LLR work. If the file goes to 700k or less, there's little point in more sieving. Mini-update: 45 at 680k, paused for 800k work 93 at 680k, paused for 800k work 197 at 882k 201 at 640k -Curtis
 2007-07-18, 06:46 #24 gd_barnes     May 2007 Kansas; USA 1038510 Posts k=289 verification to n=520K complete I'm finally done verifying the entire range of n=260K to 520K for k=289. No primes were found other than the two previously found by Bo at n=501991 and 509401. The only consolation is that I got to report them on Prime Search since Bo is not coordinating with anyone. Ah well, it's nice to know that our list is complete to that point. Needless to say, I'm not reserving this k. Gary

Edit: I just started a new thread about k=105. Gary Well done! I updated the k<300 stats page. Last fiddled with by Kosmaj on 2007-07-21 at 03:34

Please note that this k is incorrectly shown as unreserved on the k<300 page.
