[QUOTE=Mini-Geek;139527]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*2^419082-1 AES
451*2^419059-1 AES
831*2^419018-1 AES[/code]Oh well, I got a nice triplet of primes now, and they're a lot bigger! :smile:[/QUOTE]

only for another info:
i found from Team Drive #1 a quadruplet in difference of 123 at n=340k:
645·2^340424-1, 909·2^340456-1, 579·2^340540-1 and 685·2^340547-1!

Congrats on finding the 400th prime by Primesearch!! What an accomplishment in just over 7 months! Thanks to everyone for your efforts!

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 top-5000 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:

Let me know of any problems that you see ([EMAIL="caldwell@utm.edu"]caldwell@utm.edu[/EMAIL]). A record slow period for prime submission!

Sorry, I have to join you on the 72-hour status list for top-5000, lol:

My first prime for NPLB

635*2^541112-1 is prime ‏(‎162894 digits)

Found on 2008 Sept. 5 at 08h26m UTC (noticed by me at 22h28m) using my AMD Athlon 64 X2 Dual Core Processor 6000+ (with 2 GB RAM).

Congratulations on your first NPLB prime, which also happens to be our largest yet (that is, not counting any PrimeSearch primes found outside of "official" NPLB efforts)! :grin:
