Well.... they MIGHT be at 79,80,81,82 and 83k respectively...
I MIGHT be off by some amount too... Don't give up :)

Willem, Even though you stated it, it took me a while to figure out that you were actually working on the "prime" riesel conjecture for this base. At first, I thought you had the wrong base. Unfortunately I won't be able to show the prime on the web pages as they currently exist since the "regular" conjecture is only k=3226. At some point, I'll create separate pages for the prime conjectures and make them a subproject. Of course I'll show the prime at that point. Gary

I'll start on double checking at some point, when that is done I'll post the latest version. Willem.

Found a nice big juicy one for Sierp. base 23!:
8*23^119215+1 is prime! This is also my first top5000 prime for a nonpowerof2 base. Last fiddled with by mdettweiler on 20081215 at 02:22

This now becomes one of an amazing 7 bases <= 32 on the Sierp side that only have ONE k remaining! Those last k's are about as stubborn as they come. All except your k=68 have been searched to at least n=195K. Gary

Be my guest. I have all that I can handle now, especially since KEP gave up the Riesel base 3 conjecture. I still haven't reviewed the recent efforts on it to include them in my pages yet. Gary

The chance one of the bases gets proven is rather high if you do it this way ...

This could actually be done but we wouldn't want to do it with LLRnet because Phrot is likely 3050% faster than LLR and as Max said, LLRnet can't handle more than one base at a time. What we would have to do is create a big ABC file with multiples bases in it that can be fed into either PFGW or Phrot. That way, many bases could be tested at once. That said, the specific bases are at such widely varying test depths, ranging from n=100K to 400K that we couldn't really do it to prove these particular conjectures per se until we evened them out a little more, which would take quite a while. But we COULD do such a thing on k's for mutliple bases in whatever other manner that we choose as a team effort. Perhaps both base 19's at once since they are both at n=25K. Or several of the bases > 32 that are currently at n=10K all at once. There are myriads of possibilities. All of that said, due to many things going on at NPLB at the moment, I wouldn't want to coordinate such an effort for several months yet. Before embarking on such an endeavor though, what we really need to do is have a major team discussion about some goals for CRUS. We don't really have any other than the little "minigoal" that I made to get all of our powersof2 bases up to n=600K base 2 by year end. Right now, we're just kind of searching willynilly hereandthere because us admins (namely this one) haven't really had the time to put some direction to the project.
