Prime found

Earlier today, team member Thomas Ritschel informed me that he had found a probable prime and had twice proved it prime, with Proth.exe and PFGW. He has now submitted the number to the top 5000 primes and this 70,671 digit prime goes in at position 481. Well done Thomas with your first submittable titanic prime! The number is:

3*2^234760-1

Congratulations to Paul Jobling who found a prime number :D

It will go in at position 134 in the top five thousand primes table. The number has 124,880 digits:

3*2^414840-1

Allright! ;)

Hopefully you get a few more, under a million n.

Now 15k is challenged

Sergey Kochergin's LLR result file contained a nice suprise when I checked it:

3*2^584995-1 is prime! Time : 4435.629 sec.

This special number has 176,102 decimal digits and will go into the top 5000 primes at position 102 :)

Paul,
How do you start a project on the primepages.org website such that people submitting primes from that project can give credit to the project.

The Project I am working on is located at
www.geocities.com/eharsh82/

We just found our first prime!

Thanks,
Citrix

For a start, go to:

http://primes.utm.edu/bios/submission.php

You will probably need to create a "New Pover Account" and then maybe email Chris Caldwell through "mail editor" at the side of this page. Good luck!

I have just recieved an email from long-standing participant Luigi Morelli (ET) informing me he has found a new 321 prime. I am so glad that Luigi and his 1 GHz Athlon have eventually found a prime, one with 219060 digits

The prime is:

3*2^727699-1
