:george::george::george: EXCELLENT!! That's HUGE and by far the biggest for NPLB! Nice find Cruelty! :smile: 
Thanks :smile: It's also the largest prime for PrimeSearch so far :whistle:

Wow! Nice prime! Congrats!
That'll probably stand for a while as PrimeSearch's largest prime on the Top 5000.

This now moves Primesearch ahead of the 12121 search into 11th place on score on the top5000 site. That was a BIG effort to move from 12th to 11th! By comparison, moving up 2 more places to 9th should be relatively easy and should be accomplished a little before we hit n=600K on our 2 main drives assuming no big primes by the 2 projects just ahead of us. One of those projects has not had a prime in 4 years and the other has not had a prime in 7 months so that seems unlikely. Gary

If I had to guess, I doubt there are 2 primes so close together for ANY n>200K for all values of k<=1001.

Interesting. So yours are the closest together for n>265K. That's remarkable for n>530K! Of course Primesearch does not have a lot of primes for k<300 and is missing some for k>300 that are reserved by others there but found by us. You'd have to use a recent k<300 page (I keep one updated at all times) or try searching the top5000 site to know for sure, which would be very time consuming. Gary

Gary[/quote] My first idea was to look at the top5000 site, but it has so many primes of so many forms that just limiting it to riesel base 2 k < 1002 would be difficult, not to mention it wouldn't have the full list of < #5000, which would be needed to look down to n > 200K. Here's the top of the CSV file I worked up to see the gaps: [code] 261255 0 217588 0 464001 1 458098 1 234304 1 343303 2 314000 2 307794 2 286103 2 246354 2 215859 2 357331 3 287537 3 215614 3 374455 4 278054 4 259537 4 251754 4 222606 4[/code]So, mine's not the smallest n gap n>265K, I was just pointing out the two that had identical n's. Mine's the smallest [B]ngap[/B] for n>464001, but for the smallest [B]size[/B] (# of digits and what they are) difference, you'd have to check the k values and multiply the number out and everything. But yeah, regardless of past primes, that's quite an amazingly small gap, and I'm glad I got it. :smile:

I know you had some dormant reservations for quite a while. As is the nature of randomness, everything evens out in the long run. In this case, had you not chosen to take the higher nrange with all nvalues at the higher fftlen, you likely wouldn't have gotten the nice pair or 3 within just an n=600 range. Gary

Gary[/quote] Yep, the randomness of primes is annoying at times and so so much fun at other times (depending on how it's treating you, of course :smile:). The gap between the 3 is actually just n=120. It's part of a n=600 range I reserved, as you know and pointed out, but the distance between the first of these primes and the most recent is only 120. Well, it makes up for that mistake Anon made a while back that gipped me out of 3 primes (he didn't notice my reservation and sent a range which I partially reserved to an LLRnet server, which promptly returned 3 primes in an n=64 part of the n=100 range I should've had). Those primes were: [code]615*2^4190821 AES 451*2^4190591 AES 831*2^4190181 AES[/code]Oh well, I got a nice triplet of primes now, and they're a lot bigger! :smile:

Carlos, In addition to getting NPLB's 400th prime on the one before this, I think you've just accomplished something that I've never seen before. Your two primes here are the ONLY two primes on the status page at the top5000 site. That means that they are the only two submitted there in the last 72 hours. That looks very funny but it's cool that they are yours and NPLB's primes! :smile: Edit: I just now noticed this comment on the page from Prof. Caldwell so I guess this is the first time they've seen it also: [quote] Let me know of any problems that you see ([EMAIL="caldwell@utm.edu"]caldwell@utm.edu[/EMAIL]).

[quote=MiniGeek;141271]639*2^5341591 is prime![/quote] Good deal. I was worried we weren't going to find any primes with the rally. I'm estimating that we tested ~30000 k/n pairs with the rally so would have expected ~5 primes. Finding 2 is not extremely unusual but finding zero WOULD have been! Regardless, we knocked out quite a large chunk of work. Thanks to everyone who contributed! :smile: The participation was better than I expected on such a short notice. Gary
