Mersenne: M727 factored!
M727, the smallest Mersenne number with no known factor, is done.

RE: Mersenne: New v21 beta
George, This is a little strange, but the installer fails to run under Windows XP (final)... I get two error messages from the Side by Side service (which controls the concurrent installation of multiple versions of .dlls in the system directory): Syntax error in manifest or policy file C:\Documents and Settings\eoconnor\Desktop\p95v21.exe on line 1 Generate Activation Context failed for C:\Documents and Settings\eoconnor\Desktop\p95v21.exe. Reference error message: The operation completed successfully. Getting the .zip and manually doing things works fine, and prime95 itself runs without problems. I have no idea what's up with the installer. I'll try to do some digging into the SxS stuff later today. -Ethan O'Connor [EMAIL PROTECTED] -Original Message- From: George Woltman [mailto:[EMAIL PROTECTED]] Sent: Wednesday, August 29, 2001 10:53 PM To: [EMAIL PROTECTED] Subject: Mersenne: New v21 beta Hi all, The world's longest beta test continues. New beta of prime95 is at http://www.mersenne.org/freesoft.htm Linux and NT service version has not been updated yet. This release has a new menu choice ... Options/Benchmark. The page http://www.mersenne.org/bench.htm has been stripped of all version 20 benchmarks for Celeron 2, Pentium 3, and Athlon processors. I need version 21 benchmarks for these CPUs to help me populate the new benchmarks page. Thanks! George P.S. Sorry for the long beta period, I haven't had a lot of free time lately. _ Unsubscribe list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers ** This email, and any files transmitted with it, are confidential and intended solely for the use of the individual or entity to whom they are addressed.

They have a new version that supposedly corrects some XP issues. I've rebuilt the setup program and uploaded it - give it a try. BTW, I give Ghost Installer very high marks for features and ease-of-use. Furthermore, free is a pretty good price! Highly recommended.

RE: Mersenne: New v21 beta
George, That did the trick! No problems with the installer or the application now. -Ethan -Original Message- From: George Woltman [mailto:[EMAIL PROTECTED]] Sent: Thursday, August 30, 2001 12:56 PM To: Ethan O'Connor; [EMAIL PROTECTED] Subject: RE: Mersenne: New v21 beta Hi Ethan, At 10:05 AM 8/30/2001 -0400, Ethan O'Connor wrote: This is a little strange, but the installer fails to run under Windows XP I just went to ghost installer's web site.

Mersenne: Windos XP: Start at Bootup
This option seems no work on WindowsXP in one of my computers, the only one with WindowsXP. Is it so, or there is a problem with my system?

Anybody on the list that saw my post back in July of last year... knows that from the statistcal anaylsis that was done at that time... I posted the following for M727: M727 - 94.3716% probability - 2 factors M727 - 52.8693% probability - 3 factors M727 - 6.0014% probability - 4+ factors M727 - 91.1834% probability - 313-bit min. factor size M727 - 93.0447% probability - 428-bit max. factor size M727 - 21.7336% probability - highly composite factors Now we know that M727 has 2 factors... and the factors are 326 and 426 bits in length, respectively... Preliminary testing also shows that ( factor - 1 ) is NOT highly composite (having many, many factors)... Would anybody care to verify the data I posted back then for M751 M751 - 83.8467% probability - 2 factors M751 - 74.2974% probability - 3 factors M751 - 19.5801% probability - 4+ factors M751 - 87.2999% probability - 281-bit min. factor size M751 - 81.0003% probability - 526-bit max. factor size M751 - 30.1716% probability - highly composite factors Eric _ Unsubscribe list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers

Is it so, or there is a problem with my system? I don't have Windows XP. Are other XP users having trouble with the new Start at bootup menu choice? Are NT/2000 users having trouble? Windows 95/98/Me users should be OK because this is the old Windows 95 Service menu choice. It used to be greyed out for NT systems. I renamed the menu choice and tried to make it work reasonably well for NT/2000/XP users as well. -- George _ Unsubscribe list info -- http://www.scruz.net/~luke/signup.htm Mersenne Prime FAQ -- http://www.tasam.com/~lrwiman/FAQ-mers
