The "100Million digit prefactor project" page is now up :banana:

The url: [URL=http://www.geocities.com/onehundredmdpp/index.htm]http://www.geocities.com/onehundredmdpp/index.htm[/URL] , to bad geocities does not allow starting their pages with numbers.

We have several folks now working on the project and could use some more warm CPU's.

Follow the link to see where we are.

Nice job! :wink:

BTW, Will Edgington has released a new "facpriks" file dated June 25, 2004. It seems that now it has many more factors above 79,300,000 :rolleyes:

Hi,
I am one of the "new folks" :grin:

I am currently running some ranges from the "wide" phase (up to 55 bits) + individual exponents from the "deep" phase (up to 62 bits).

For my first individual exponent (332192953) the program found a factor quite fast :banana: (beginner's luck is not a myth :razz: )
No factor found between 2^55 and 2^62 for 332192957 and 332192969 though :no: (Now working on 332193019)

segmtfault 2004-06-30 17:27

M332193019 no factor from 2^55 to 2^62.

Reserving M332193047.

segmtfault 2004-06-30 21:12

M332193047 has a factor: 2926561826311184081 :banana:
(no other factor found between 2^55 and 2^62)

Taking up M332193053.
