Out of curiousity, I am wondering if the source to various sieving programs will ever be released by their authors. I do not know how to go about writing a...
As we're flatly refusing to have a proper winter in Finland this year, I thought I might fly south, and Mr. RyanAir decided that I should visit Dublin again...
... I had not heard the name "multisets" before. I can use that terminology in the future. multisets if multiplicities are allowed, and sets if multiplicities...
Matrix Factor Element Sets A Matrix Factor Element Set is defined recursively as follows. Any set of distinct non negative integers which includes zero is a ...
How can one prove the primality of a PRP when every program I've tried is unable. To form of the prime is XYYX such as 2^2007+2007^2. I have many PRP's to...
Does anyone know something about Georges Brougnard prime gb- sequences ? Definition : -- gb[0] := any prime > 2 -- if gb[n] = 2 (mod 3) then gb[n+1] : =...
A beautifull evening, I try to give you a sufficent proof for primes p:=x^2+x+1 p:=x^2+x+1=x*(x+1)+1 with p = 3 mod 4 => 2 appears only one time as divisor of...
Hi all; Can someone point me to a site with the proof for the following (I Googled till blue in the face because:) I dont know the English word for what in...
It is an old problem in this forum, how much primes a polynomial does represent. Admissible irreducible polynomials with integral coefficients and positive...
Hi , all , Within the past several years , the option -oe+ , which broadcasts its "stdout" to stdout and a file , has apparently disappeared ( can something...
I have posted a paper ¡°There are infinitely many primes of form a^2+1¡±£º http://www.paper.edu.cn/privatetools/released/download.jsp? file=200611-738 ...
Hi Does anyone have a spare copy of Zmath.xla, the Excel add on that Joe Crump designed a few years back. It is still the best add on for people who want to...
I've discovered a prime number so large that it can't be written down in finite time: pi with the decimal removed. If it's irrational, and the decimal's...
I have been participating in Joe McLean's Keller prime search. Unfortunately the email address I have for him appears not to work any more, and I'm unable to...
Hello all, I have written a proof of the Riemann Hypothesis available as a preprint for comment and feedback prior to resubmitting for peer review. The last...
Hi all, I'm curious to see whether the properties of polynomials with only prime exponents have been studied or not. And specifically, how would their Fourier...
For each of the odd primes p < 10 000, I calculated the number q as follows. r = int(5 * p/12) m = r - p%r q is the largest odd factor of m. There are 1228...
Let A and B be two sets of n and m positive integers, respectively. We want to know if {(an element of A) - (an element of B)} covers the entire interval of...
I'm trying to resuscitate some old code for testing proth-like numbers (in part so that people with non-x86 architectures can participate in such searches),...
I came close to constructing a factor algorithm based on algebraic identities. How close did I come? The algorithm broke at the following step: I have known...
If 1/n has the period n-1 then n is prime(n is a natural number). Of cf course there exist primes for them the condition don't hold. But if it hold, n must be...

Hi , all , What is the largest number ever located by a prime hunter which passed a pseudo-primality test , but ultimately proved composite ? Cheers , Walter ...
