 2005-11-24, 12:44 #14 grobie     Sep 2005 Raleigh, North Carolina 337 Posts question, with the above k's are we searching the whole k for all primes or are we just starting at reportable prime n value? Also do we need to send results to someone or just save them? I know my question is a matter of choice but I just want clarification what RPS recommends. Thanks
 2005-11-24, 14:24 #15 Templus     Jun 2004 2×53 Posts The minimum n-value that the prime-database accepts lies around n=203000. So I made a sieve file for 230000203000. I save my own results files

There were reports of wrong results if it's not checked. I also log the removed numbers (Options-->Log the numbers removed).
IMO: This is some important information, perhaps it should be put somewhere on this forum as a guide.
Besides what do you mean by wrong results? Does newpgen fail to detect factor (not critical) or falsely reports factor (critical).

You shouldnt have to test 1 thru 10k in the above k's. Or am I wrong?

 2005-11-24, 20:42 #18 lsoule     Nov 2004 California 23×3×71 Posts The range n=0-10k has already been tested for these ks. My usual practice is to try is from the minimum reportable range up to 250 or 300k. If it's productive, I'll then go back and test the 10-200k range. There is no real requirement here - just do it the way you find most interesting.

If some one is intressted to continue sieving/llr'ing just make is a bit easier and grab the following two: http://1202.org/download/k15_8288233.out http://1202.org/download/lresults.txt Last fiddled with by BotXXX on 2005-11-25 at 13:25

 2005-12-05, 03:09 #22 NiceMedTexMD   Jun 2004 2A16 Posts Could someone explain to me in basic steps (i'm not as computer literate) how I would reserve a k, run it for a few weeks, and hopefully find a bunch of primes? I know how to run the LLR program, but that's about it so far... Mike...
