The lower area seems to be growing again, although not too fast. If they're still there, I'll knock out 25004000 in a couple days. That's around 100 candidates, but also includes some "##" troublemakers.

I've spotted two pairs of PRPs where proving the first would enable a N1 proof of the second:
Code:
1100000001217007748 ((3^666*665+11)/8342630578361)/40 1100000001216564194 (3^666*665+11)/834263057836 Code:
1100000001217042397 ((2^1062*1061+19)/7122542872591)/24 1100000001216000549 (2^1062*1061+19)/712254287259

We're still over 1k candidates below 3000 and the area from 2500 to 4000 has been cleared, except for three "##" numbers. I'm going to work the 2xxx candidates in with my other work in a little while. If no other posts show up here telling me to "cut it out!" I'll move further down, maybe to 1K. Other than possibly working the two 3xx candidates that Chis brought up, I plan to leave those below 1K for new workers, unless there's a flood.
All comments welcomed...

I can take all below 2K. Just give me some time to set it up, expecting to start in a few hours!

Once factordb has processed Primo certificates for the first of each case then clicking on primality for the second should bring up a button to prove it prime. Just click that and the job's done. But it might get clicked by someone else fairly quickly so don't leave it too long. Chris

The buttons show up even if there is a primo certificate. Clicking it will do the proof with pfgw that will "override" the primo proof. The certificate would still be listed in the uploader's certificates list, but not on the prime's page. Either way, primoproving 310dd numbers takes less time than us writing these messages, so it wasn't a measurable "waste" of time at all really.

The first batch (1000 numbers) was finished midnight and uploaded shortly later. The next batch (400 numbers) is in work an will be uploaded in 12 hours. After then only a few (~30 numbers) are left in the range.

Three more 2xxx candidates showed up overnight and I added them into my mix. After that and Dennis' work, the lower region should be looking good, so I'll go back to the 5xxx area and let the smaller ones build up again.
Agreed, but I'm very lazy.

Here's another pair of PRPs where proving the smaller would enable a N1 proof of the larger:
Code:
1100000001263132416 ((2^1024+12^611)/326671)/2 1100000001262412076 (2^1024+12^611)/32667
