Like I said at CRUS after he found a prime almost immediately at n>119K for Sierpinski base 6 (after we had only 1 prime in an n=20K range prior to it), Ian is our golden boy! :smile: 5 primes already combined on 2 different drives for n>600K! Remarkable is all that I can say.

It's finally time for someone else to snatch one:

539*2^602564-1 is prime

This makes me wonder if we just lest Ian do the entire 5th, 6th, and 7th drives, will we get 2-3 times as many primes that way? lol


:smile: Gary

587*2^605050-1 is prime!
My first prime in the 5th drive and first above 600K, and largest by a large gap (n=57585, my largest gap). The NPLB leading edge is nearly into the top 1000 of the Top 5000 list. (my prime, at the moment, ranks/will rank once verified as 1107, rank 1000 is 35*2^634402-1)

665*2^601262-1 is prime! Time : 474.0 sec.

409*2^606805-1 is prime

467*2^607118-1 is prime

387*2^782853-1 is prime 235665 digits

675*2^603636-1 is prime


A couple of interesting side notes on this one:

1. This is the 8th prime for k=675 for n>260K. Benson found all 7 of the primes for n=260K-600K so this is the first new prime found by NPLB for this k. When I saw that I had found it, I thought it must be confirmed but Benson had stopped at n=600K where the Primesearch site ranges stopped at so NPLB gets this one! :smile:

2. This k is on a tear with 2 primes in an n=4K range, 3 primes in an n=25K range, and 4 primes in an n=74K range.

Delete all primes for n<540K posts?
 

To all,

I am recommending that we delete all primes posts for n<540K. Can anyone think of why we should keep them? The info. is compiled in the 1st post of the applicable threads here as well as Karsten's drives pages and k=300-2000 page.

I think it's time to do a little clean up as well as reduce my posts count. lol There are some people who seem to think that I write so many posts only so that I can lead the total # of posts count. I couldn't care less and would like to dispell the notion. Deleting some posts here would be a way to kill 2 birds with one stone.

Hmm...yes, that probably would be a good idea. Another option would be to merge the posts into one so that we could still retain the info...but, yes, you're right, since it's all already recorded elsewhere, it shouldn't be a problem to delete them.

I'll give until 6 AM GMT Monday morning for anyone to voice any objection to me deleting primes posts in this thread for n<540K. I'll then start hacking. :smile:

I will keep most of the general ongoing commentary posts. Some of them contain interesting info. that will be nice to have for future reference like the most primes found in a day or the most different people to find primes in a day, primes that are closest together by n-value, etc.

When we pass somewhere in the neighborhood of n=640K-650K on our new drives, then I'll delete all the primes posts up to n=600K after letting everyone know first.

finally a cleanup
this will make it lots!! easier for someone to read all through this thread and read any helpful bits of information
would it be too much to ask for reservation posts in the drives' threads to be deleted to make it easier to read there as well
there is lots of useful information scattered throughout some of the longer threads on the NLPB and CRUS forums but they have so much junk in between that they are hard to find
i would almost consider trying to make an index of some of the most helpful conversations
