Mersenne Digest Tuesday, June 3 2003 Volume 01 : Number 1072
---------------------------------------------------------------------- Date: Sun, 01 Jun 2003 12:06:08 -0400 From: George Woltman <[EMAIL PROTECTED]> Subject: Mersenne: 40th Mersenne Prime Found (probably)! Hello all, This morning a new Mersenne Prime was reported to the primenet server. It will be the new largest known prime but is less than 10 million digits. For those not familiar with the process regarding new prime discoveries, here is what will happen. The discovery will be verified using a different program and different hardware. The discoverer and the exponent will be kept secret until verification is complete. This is done for two reasons: 1) It reduces the incentive for a malicious user to hack prime95 to report a bogus prime, and 2) It makes it easier to interest a newspaper in reporting the find (they are breaking news rather than reporting 2-week old information). Congratulations to all! New primes can't be found without the thousands of unsuccessful tests contributed by everyone. Enjoy, George _________________________________________________________________________ Unsubscribe & list info -- http://www.ndatech.com/mersenne/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers ------------------------------ Date: Sun, 01 Jun 2003 12:17:31 -0700 From: Gerry Snyder <[EMAIL PROTECTED]> Subject: Re: Mersenne: 40th Mersenne Prime Found (probably)!

Can you give us some idea when this will be complete? > Enjoy, > George Daran G _________________________________________________________________________ Unsubscribe & list info -- http://www.ndatech.com/mersenne/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers ------------------------------ Date: Mon, 02 Jun 2003 23:34:15 -0400 From: George Woltman <[EMAIL PROTECTED]> Subject: Re: Mersenne: 40th Mersenne Prime Found (probably)!

I wasn't going to do one but Ernst has started his and suggests comparing residues every 1,000,000 iterations. A good idea, so I've just begun my test. Ernst will finish his official test in the June 20-21 time frame. I should finish sometime on the 11th. _________________________________________________________________________ Unsubscribe & list info -- http://www.ndatech.com/mersenne/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers ------------------------------ Date: Mon, 02 Jun 2003 21:59:01 -0700 From: Brian Dessent <[EMAIL PROTECTED]> Subject: Re: Mersenne: 40th Mersenne Prime Found (probably)!
