[QUOTE=MyDogBuster;262853]Here it is:

20049*2^1687252-1 is prime

Just submitted it to the good professor.

Another one over 500K digits (507918). We are on a serious roll here.[/QUOTE]

OUSTANDING!! Congrats Ian! This also knocks out k=20049 for bases R4 and R16.

This shatters 2 records for the project:

Largest 3 primes found in 2 days!

4 of the top 5 primes found in 5 days!

Amazing.

Most interesting--a prime (pardon the pun) example of a "prime bunch" there. :wink:

Congratulations on an awesome find!

85287*2^1890011+1 is Prime

Just to give everyone a heads-up: I will be out of town with semi-limited internet access for the next week at a family reunion. See [url=http://www.mersenneforum.org/showthread.php?p=265960#post265960]this post[/url] over in the NPLB forum for more details. At the rate we're processing on port 1300, I'd estimate a good chance that it will dry out sometime while I'm away. Since we haven't yet decided on what to do next for this mini-drive, I'm unable to pre-stock the server with adequate work to last out the week; if a decision is reached before 2 AM or so tonight, I should be able to get it loaded before I leave, but otherwise I can't make any promises. I'm pretty sure I'll be able to load the server from my laptop while away, unless the job involves tricky sorting-out of sieve files (like the current base 2 batch did), but it may have to wait until the second half of the week because my laptop will be busy serving another purpose initially. (Long story--actually kind of a humorous one but it's rather too long to put in this decidedly unrelated thread. :smile:)

I have to move my core later today so I think there will be work for some more days.

Squeaked in one (likely) last prime before n=2M:

[URL="http://primes.utm.edu/primes/page.php?id=100942"]148323*2^1973319-1[/URL] is prime!

:party:

This knocks out k=148323 for R2 odd-n, and is currently the 3rd largest prime found by CRUS. (And it's far and away my largest personal find! :smile:)

Now wouldn't it be really something if we found another one before 2M... :grin:

Max :smile:

Yea Max. Nice find. Everything seems to come in pairs or triplets lately so there is one or two due. :max:

NICE!!

:bow wave:

I added some core on it so I hope they are done to 2M tomorrow.

Lennart

The drive is complete to n=2M.

Substantial sieving is needed for testing > 2M and there are several additional k's that will be added. It will be a while before such an effort is started.
