 Congratulations on a nice prime and a proof to boot!By the way, this prime is big enough to submit to the Top 5000 largest primes website. If you need instructions on how to do this, feel free to ask around. (If you've done this before by chance, then you'll need to credit your proof code to "[your name], CRUS, LLR, Srsieve" with LLR as the proof program since that's what it seems you used based on your output file.)

one down for R30
225*30^158755-1 is 3-PRP! (821.7957s+0.0168s)
Those square k's are good for something after all.

Whew, THAT has been a tough base to find primes for. Although we aren't completely filled in on all k's up to n=158K yet, we are at n>=110K on all k's and that was the first prime found since n=~50K. There were so many stubborn squared k's remaining on R30 that I was beginning to wonder if there was some sort of monsterous or infinite covering set or some kind of inordinately complex algebraic factorization that we were somehow missing on them. Well, that's why we test these things: to prove that they all have primes at some point, which is hideously difficult in many cases. Gary Last fiddled with by gd_barnes on 2010-04-01 at 23:47 |

I have renamed this thread to "report top-5000 primes here". Previously the 1st post said to report "large and small" primes here but I think it caused confusion on whether people should report their primes in the reservation/status threads or here. So I've tweaked its wording accordingly. I've also renamed the reservation/status threads to reservation/status/primes threads.
What I'm attempting to do is get all information about the bases except top-5000 primes into the various bases 33-100, 101-250, etc. statuses/reservations threads. At times, I've found it very difficult to conjure up primes that were previously found because they were in multiple places. If people attach a file with primes, I'll usually remember to save it off but if people just list them, then I frequently don't remember to save them off. It's OK what people do either way. I just have to make sure that I have some sort of accounting or way to get back to previously posted primes if I don't save them off. I have now moved all posts to their respective reservation/status/primes threads. I took into account whether the prime(s) were top-5000 at the time that they were reported. To be more specific, please report all top-5000 primes here that are NOT found in team drives. The team drive threads are still intended for all statuses and primes related to that base after the time in which the drive was started, regardless of size.

170*80^148256-1 is prime http://primes.utm.edu/primes/page.php?id=92430
This leaves 3 k's on Riesel 80 (I'm taking them to n=200K) |

Nice one Ian! As the first prime since n=16237, those final 4 have been extremely tough on that base.
Shoot me your search depth on the remaining 3 and I'll reflect it on the pages. |

These primes were also reported with their completed range.
4852*53^85259-1 http://primes.utm.edu/primes/page.php?id=91945 536*53^85998-1 http://primes.utm.edu/primes/page.php?id=91994 172*53^90603-1 http://primes.utm.edu/primes/page.php?id=92168 3058*53^96037-1 http://primes.utm.edu/primes/page.php?id=92328 382*53^99675-1 http://primes.utm.edu/primes/page.php?id=92467 I hope I covered all your bases Gary.

Impressive amount of work Ian. Well, you haven't gotten all 2046 bases covered yet but you're working hard on them.
