Nice finds, congratulations. Pity they don't divide the MMs.
I stopped my search, no resources, but I may resume later.

You will be welcome by then... there are a lot of possible million digits candidates out there...

Updates

MM34 has been tested for factors up to k = 1,500,000.
MM35 has been tested for factors up to k = 1,453,840.
MM36 has been tested for factors up to k = 110,132.
MM37 has been tested for factors up to k = 310,768.
MM38 has been tested for factors up to k = 113,500.
MM39 has been tested for factors up to k = 100,520.

MM32 aand MM33 are under scrutiny up to k = 2,000,000.

Mark Rodenkirck's gmp-fermat has been upgraded to work on the range MM13 (521) - MM25 (23209). It's available from the download page.

Happy factoring!

Luigi,

For MM36 how many candidates are left for 110,132<k<500,000?

Carlos
7692 exponents to get k = 500,000
3930 to reach the limit of MM37 (k = 310,769)

Hey Luigi, following my above post in another thread which maybe you don't read often (but you can click the quote to see the discussion, if you like), I got some requests on PM, for "factor5 executable". People claim it is not easy to find it with google, because the name is common for other things, and I just tried the link to the home page on mersenne wiki, but that points to moregimps.it which is broken (BTW, can some mod fix the link? I can't remember my password because I didn't do any editing work there for ages). I tried your other pages but there is no mention to factor5 anymore. The only exe I have is here attached, I don't have any sources. Can you point us in the right direction? Are there any "more recent" developments in this direction? What does the "not suitable for very small exponents" mean? (i.e. can it be used to crunch 1277 from 57 to 58 bits, for example?)

---------
Disclaimer: to whom it may concern, please scan the exe file with your favorite antivirus program, in case you decide to use it.

Yes, I remembered right, that you talked about a new, faster build, in the past! That is why I posted. Can we get a link to exe or src?

Hi LaurV, sorry for the late answer (I have been kind of "busy" last year).

Due to the number of websites I manage, the raise in managing prices and the problems I had last year, I decided to take moregimps off the web.

Temporarily.

After a number of requests related to the projects it hosted, I will (try to) restore it under a new domain (if I can find the right backups).

As per the updates, unfortunately they are still all in my mind, so version 5.01 is the one to go at the moment. Anyway, building it under the last GMP/MPIR version offer some slight performance enhancements specialy for the newer processors.

Luigi
