It will likely be Monday before I can get everything updated and files posted as a result of the primes found here. Max, can you at least update the 1st post here? Be sure and reduce the k's remaining and increase the primes found in the 1st para.

Ian, if you want, on Monday, I can send you the entire remaining files and you can test them until you're bored with them. That'll save me some admin time and you some time for posting reservations and reloading/restarting your cores on the various ranges.

I'll make an effort either early morning or early afternoon Friday to post the k=175M-200M file for n=50K-60K so that you can take if you want it. That way, you can bring everything up to n=60K and if you want to continue from there, I could send you the one bigger file.

Okay, sure. I'll do it sometime today; bug me if it's not done by the time tomorrow rolls around. :smile:

Edit: Done. It took me a little while to figure out how everything was organized in the first post, but I think I've got it now. :smile:

It's quite confusing at the moment and I don't intend to leave it that way. For consistency, it should be sorted entirely by n-value but we could be different and sort it entirely by k-value this time. It's just been easier to post them as they came in and not resort every time. Eventually I'll get to it.

Ian,

I've now posted k=175M-200M for n=50K-60K. I've also removed all k's with primes for my internal files of k=100M-125M for n=60K-100K based on your primes for that k-range for n=50K-60K.

I could now post a file for k=100M-125M for n=60K-70K (with 53 k's remaining) but I'll hold off and see what you want to do if you end up finishing all 4 k-ranges for n=50K-60K.

I guess I beat that Monday deadline. :-) I just didn't want to hold up these base 3 efforts since they haven't been too popular.

Why don't we just play ring-around-the rosie with the 4 ranges. That way you don't have to delete any k's out of posted files. I'll probably go all the way to n=100K on all 4 k ranges. May as well finish the drive.

Not sure exactly what you mean but based on the context of it, when you've finished all 4 k ranges to n=60K, I'll send you the entire file for n=60K-100K for k=100M-200M with all k's with primes removed. It might be a couple of days afterwords.

Sounds like a plan.

That's amazing that there are no primes for that range for n=53330-60000. I had to check the results to make sure you hadn't accidentally cut off the list.

I thought it was pretty strange also. A nice hole in the middle of a fertile valley. When I cranked up 150M-175M, I got one right away back near n=50082. I'm nearing that void area again with this range. It will be interesting to see how wide it is.
