Hi, I've read the "new Mersenne Divisors conj." thread, and I propose the following test for Sophie Germain primes > 3 that does not require 2 different cases...
I think that I found a new Mersenne Divisors conjecture ???; I couldn't locate it on the web, but that doesn't mean anything. Let p == 1(mod 4) be prime. 2p +1...
Hi All, Not sure how to go about listing them but the TPS searchers have 2 more AP3's among their findings 01808289789*2^333333-1 100353 L212 Mar 2007 ...
This is a bug fix release for WinPFGW only. The Linux and Mac versions were not affected. With this release WinPFGW now correctly displays the "Line in...
There are significant behavior changes to this release of PFGW WRT to the handling of sumout/roundoff errors and the use of the -a switch. 1) The -a swith no...
The idea that for a great many quadratic equations the application of the simple function 5r^2 - 4*C(y) over relatively small tightly ordered intervals (valid...
You can d/l PFGW 3.2.7 for Windows from here: http://openpfgw.svn.sourceforge.net/viewvc/openpfgw/pfgw_win_3.2.7_20100107.zip?view=log Mac and Linux versions...
APR-CL was written on a CDC Cyber by Dik Winter when fellow CWI-er Arjen Lenstra introduced him to his and Henri Cohen's improvements to traditional APR in the...
I have divided the primes into 3 groups working on a general format of 36mn +/- 6m +/- 6n +/- 1. Below is a simple and I think efficient algorithm for testing...
I do not know too much English, but with a translator program I am writing this post. I want to ask a question. I have also re-definition of prime numbers....
1) Fixed b^n+1 check for using fast modular reduction 2) Some prime numbers silently fail (i.e. no errors detected) when testing for primality. To address...
A decadal prime triplet is a set matching one of the four types {10K+1, 10K+3, 10K+7}, {10K+1, 10K+3, 10K+9}, {10K+1, 10K+7, 10K+9}, {10K+3 10K+7, 10K+9},...
Hi, all. Some of you may be interested in this, many will not see the point. I'm happy to discuss it. But first, I have written up what I feel to be a...
Here is a conjecture about the minimum number of primes between consecutive perfect squares that I presented Aug 8, 2009 at MAA's Mathfest in Portland,...
Hi everyone, To increase the probability of finding prime numbers I find the strategy of using four different terms for the same integer constant very useful....
To the best of my knowledge, I think that I have created a new prime number conjecture that will be proven someday. It is similiar to the Old Goldbach...
The multi-polynomial part of the multi-polynomial quadratic sieve. Hello Prime number friends. I've worked out this part of the multiple polynomial quadratic...
Sat Jan 3, 2009 10:43 pm I went to solve the same puzzle as he when the realization of magic cubes occurred. I was drawing it out at Waylon's Tavern spare time...
It is noted that a squaring is not the same as a squire. Some say a squire is the attendant to the knight. And is known by the knight the pattern of its...
Hi All, Since the demise of Geocities the multifactorial search has been homeless. Now thanks to the kindness of the people at Free-DC (Special thanks to Phil...
I was looking for a yahoo group on mathematics that might solve some of my mathematical suppositions. I dont know how strict the moderator is as some of my...
Hi group, 138^196873-137^196873 is PRP for bases 2, 3, 5, 7, 11, 13, 17, 19, 31, 71 and 101. This number has 421285 digits. Moreover, 138^p-137^p is composite...
I have established the following result:- For each of the 6 currently remaining candidates for the smallest Sierpinski number, no covering set of primes, with...
I happened to look at http://primes.utm.edu/bios/top20.php?type=person&by=PrimesRank and was struck by the fact that Bouk de Water, without needing to prove...
There are lots of these. but here is another nice one by M. Chaves: Theorem. A necessary and sufficient condition for the integers n>7 and n+2 to be twin...
