Sounds to me like garbage in the file. I do not know how the "ecm" you are using was built, but it sounds like it might be having problems with "DOS" end of...
... I've solved the problem. It has something to do with the encoding of the textfiles windows uses. When opening the file (which in my idea only contained a...
Hallo, has everybody precompiled libgmp.a for windows (GNU MP)? Or knows where to find/download? I did not find and could not manage to compile myself. Best...
Has anyone here watched some episodes of Numb3rs on TV already? There is a nice review of it here: http://www.maa.org/devlin/devlin_02_05.html It's not often...
... A writer from Numb3rs called me for advice on that show and I talked to him breifly at the MAA/AMS meeting in Atlanta. He took some of my advice on dialog...
I've seen it a few times. It's Ok, especially for those who know nothing about how prime numbers apply to them. I seriously think they got some ideas for the...
Very interesting Chris, I replied before I read your reply. It seems your protest is the plot. Did you supply the equation in question? If so, please post it...
A colleague and I were once asked for General Relativity dialogue for a TV movie. The scene was predictable: genius teenager is asked questions by world famous...
... The writer told me their goal was like in "ER" not to be correct, but to sound like things doctors [mathemticians] might say. I think they are doing okay....
Until last week, the largest known CPAP-3 was 87*2^24582-1+1290n, n=0,1,2. http://listserv.nodak.edu/scripts/wa.exe?A2=ind0411&L=nmbrthry&F=&S=&P=619 Hans...
... Oh, you really should have submitted that "Andersen-canonicalized" form, 5 times over, and complained to Chris that he couldn't parse it. What's the point...
I think that I may have tested that form back in 1995, but not as far as you've gone. I will let you know if I did by tomorrow. As you can see, this number...

There was some discussion on this board a few months ago about the primality of the Fibonacci number F(37511). Has this proof been completed? Are there any...
Neither John Renze nor I found the time to write a validator for the LLL part of the CHG method. If someone wants to write such a validator and to document,...
http://physics.open.ac.uk/~dbroadhu/cert/semgpch.gp proves that a 5k-digit number, N, is semiprime, yet does not (I hope) give enough information for the...
Jens: I cannot conceive of a way of determining whether 10^999+13 is semiprime, other than by finding a proper divisor. And such a divisor probably has more...

Hello all, I don't know how works FFT in detail. Perhabs we can speed up the follow method. Example: We test , is 2^5-1 a Mersenne prime ? The exponent is 5....
Decio: I used "something else entirely". I also took a lot of care to cover my tracks. (Only Phil-the-silent is in the know, so try bribing him:-) But I reckon...
