Nice job. Now if they would only make you a moderator and allow you to move the post to first in the thread, we would be in business.

Just on this thread then. I make enough bad pun in real life.

Are you from Brighton Beach? ;-)

I`m doing the 1975 digit PRP now.

Puzzle-Peter 2013-06-22 04:41

Half of my range is gone, so I have to move it. I'll finish off 1996-2000, then work upward from there plus any new PRPs "behind my back" of 2000+ digits. I'll ignore anything that pops up below 2000.

Due to my setup that makes me download new work before finishing the last range, I am often active two or three thousand PRPs above my trailing edge to avoid overlap. ATM that means only a few digits but after the bulge (ending at 2031 digits) it's quite a lot. It will be a while until then though.

While I was busy in real life, somebody did a lot of work and actually finished off the bulge, continuing upwards as it seems. To avoid stepping on each others toes, I'll move up close to 3000 digits as Ian does not seem to be hyperactive atm.

Let's see if we can really empty the "distribution of PRPs" page...

I've seen a lot of certificates being processed for RichD and RobertS over the last month or so. A month or two ago I was doing some small ones as well as 2100-2300 digit ones from the list, but I've lately been working on some prime gaps up in the 6000 digit range instead, especially as anything under 2100 digits now gets handled within an hour or so, making my proofs usually wasted (albeit for really small amounts of CPU time).

Since this thread seems inactive, and the number in question has sat for at least several days, I am currently proving the PRP2000 with database ID 1100000000802455607 .

All times are UTC. The time now is 17:40.
