... I patched the hole with the "Lucas V" method by insisting on a Euler probable prime test: 5^((n-1)/2)=jacobi(5,n). Both the above "counterexamples" happen...
Hi, Re: David's http://tech.groups.yahoo.com/group/primeform/message/7338 firstly, some local notation: "+-" and "-+" is used throughout in a conjunctively...
The university I work at has a few big clusters of computers that I've been given permission to run prime programs (mainly llr, but also pfgw) on, and they are...
hi Joe, The videocard manufacturers are competing with each other. If company A says they can do 1 teraflop a second, then company B will say they can do 1...
I don't have much information about the price as I'm not the one buying it. I'll have to get back to you on just how much better computing works on the card....
I wouldn't say it like that Joe, It certainly isn't easy to get a good FFT going in 32 bits. It is very well possible that if your FFT is 1 GB huge and just...
Of course Joe, i posted a lowerbound. In reality there is the overhead of FFT which is for DWT like 4n + 2n log n Fact is that if the internal cache subsystem...
Hello mathfans! The numbers 5612052289.14500#/5 -1,+1,+5 is a new prime triplet with 6223 digits. For +5 you can download the PRIMO certificate here: ...
Norman, The codes for 5612052289*14489#/5+5 6223 p41 Jan 2008 5612052289*14489#/5+1 6223 c18 Jan 2008 5612052289*14489#/5-1 6223 c18 Jan 2008 are precisely the...
David, I have tried to be friendly, but if you persist, I will crunch for my own. If it is so important to get yet another extra prime ... get a life. If the...
Cedric, ... That was the only prime that I mentioned. Thank you for admitting your error. I am now able to advise Chris Caldwell how to fix it. Incidentally, I...
Hi, there were too many sloppy errors in my previous posting on "x^2-x+-Q" that I feel the need to post again to state what I intended to say: For n>5: 1.) if...
6k +-1 How do you determine rapidly for which 6k +-1 , the numbers are prime.? I want to check for numbers greater than the given number. 25964951 -- mohan...
... Well geez, that makes me feel all warm and fuzzy. I don't pretend to know a lot about primes and the math behind them, but I do consider myself an agent...
First of all, I can't use English well. However I believe one simple thing that mathematics's notes go through the whole world. I suggest some algorithm...
This is the original sieve. ??? Eratosthenes? No! I suggested one algorithm using computer. Maybe, mathod of Eratosthenes will be take kime so long. Please,...
Dear members, anybody of you known about a gigantic prime triplet project ? I have start a searching. The form is k*2^33333 -1,+1,+5 and anywhere between k=0 ...
Hi everyone! if you are interested in Mersenne and Cunningham numbers I have the pleasure to invited you to read my new web page dedicated to a new theory...
Raanan Chermoni continues running my program and has just discovered new AP23: 1172380401690583 + 1675204*23#*n, for n = 0 to 22. It has the largest term...
Hello, Group. I hope that someone can help me. This is my C program which has been modified so that the perl parser of the PFGW compiler can convert it into a...
