With CK=200 Is complete with no primes remaining. Attached are the results Edit: Nice work Mathew. This is a very high CK to prove without much testing above n=2500 (last prime found at n=3327) Last fiddled with by MyDogBuster on 2010-05-11 at 00:40 |

We didn't really talk about reservations only posts for CK<=200 like this one. This is the one remaining k=8 conjecture. I'm still assuming that you will handle them, remove from untested thread, do HTML, etc. For a quick reference on the HTML, just do a find on "just started" on the pages. Gary |

Mark,
As requested in the news thread, when people submit/Email a load of bases with CK<=200, we are asking that they also post which bases they are in these threads, one per line just as Ian has done above so that he doesn't have to do that. If the base isn't proven, then showing search limit and # of k's remaining is also needed for the applicable bases in the post. No more actual detail (primes/which k's are remaining) is needed in the posting. We're trying our best to spread the work out among everyone here. :-) Thanks, Gary Last fiddled with by gd_barnes on 2010-05-11 at 21:25 |

CK=18 complete to n=25K k=16 remains Attached are the results Edit: Mathew k=16 is proven composite by partial algebraic factors (Factor 17) You didn't have to test it. Conjecture is proven Last fiddled with by MyDogBuster on 2010-05-12 at 00:52 |
