junky · 2004-05-10, 12:37

we almost reached the 90% for the 2_1137P, that's great.
what's i'd like to know now, is what's the next number ?
another Cunningham Project's number ?
Thanks in advance.

Yes, it is another Cunningham Project number. This time it is a "More Wanted Number" and is 11^206+1 which has a 213-digit cofactor. Indeed, there are no known factors of this number other than the trivial algebraic factors.

We stand a fair chance of finding a factorization where both factors have more than one hundred digits. Only a single example of such is known at present.

any estimated time to complete tha one ?

11^206+1 ( aka 11_206P ) has started.

junky · 2004-05-14, 22:54

whats the estimated time for that project ?

Maybe it can be calculated from the information from the following URL

http://www.nfsnet.org/stats2/statsre...roject=11_206P

So far stats are 0.36% complete (27.6288 of 7500 workunits)

I expect progress to pick up rapidly now that most of the workers have been released from the previous project.

However, "the survey shows" that 7500 may be a bit low for the estimated work required. Today, I would suggest 7700 WU.

I am pleased to announce that the sieving for 2,1137+ is now complete.

We collected 46M relations which I am now in the process of reducing to a matrix to solve for the factors.

Those of you who are short on hard disk space should delete the files for the factor base by removing the projects/2_1137P_2/ folder.

Thanks to all who participated.

We are now sieving another Cunningham number, 11,206+. You might check to make sure that all of your sievers made the transition.
