R596
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)

[quote=mdettweiler;214604]Reserving R986 as new to n=25K. (I've already tested it to 10K but one k stuck around, and I figured I should at least take it to 25K before giving up on it.)[/quote]

Ian,

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.

Seeing as my bases are so small, something like this will probably be done long before I can create a "just started" page.

I'll remove it from the untested thread and make a note to myself to look out for it.

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

Fortunately I have giving everything I've done to Ian.
