I've been running Prime95 with a smaller B1/B2 and a huge exponent (M33554432). I realized this morning that the box has been stuck on the same curve for the...
From: "j_m_berg" <j_m_berg@...> ... With a B1 that low, it's quite likely that the factor, if it really exists, could be found with only trial division. ...
All, I am a novice with the Zeta Function. Could someone help me understand something... If I set S = 1, and calculate up to 1/7 and 1/7 only, Z(s) = 1 +...
... This expression for the zeta function only converges when the real part of s is greater than one. In Calculus this was called the "p-test" (at least in...
In my search for "triple double" values, I am looking for a k, such that the two power series k.2^n+&-1 provide more than 10 Cunningham Chains (1st kind), 10...
... CC more common?!? ... Gary: No simple answer to that. I would have to rerun the candidates to find out how many CC3, CC4 etc. My program only counts...
I'm many miles from home, and without my C&P, and floundering with my google searches. I don't suppose someone could provide some links, or a few quick hints...
Its been a thrill to me to use the pari to factorize large numbers. A very small observation which i made is what follows:- A mobius function M(n) is defined...
[pushing back on list] ... Anna is coming to Turku with my copy of the book today. I have had a wacky idea for a possible modification to pollard rho. I was...
... This sounds like one of the research problems in C&P. I've worked alot on it and can see some similarities to your problem. In chapter 6, research ...
hi Sudarshan, ... You might also like to try out MIRACL's factoring package below. http://indigo.ie/~mscott/#other ... According to mathworld (URL below) the...
... That's related, but the poly evaluation I'm after is at arbitrary points. The closest thing in C&P is in the research problems for exponential-time ...
I am pleased to annouce that I found the largest known Woodall prime. 1195203*2^1195203-1 is 359799 digits long It was found using my MultiSieve program for...

Mark, Congratulations on a huge and so rare prime! I just noticed on the Top-5000 status page and I was very surprised. The old record was almost 5 years old. ...
For those of you with access a PowerPC, I want to direct you to Phil Carmody's PIES project (the pies_project group in Yahoo). Over the weekend, I found this...
Please do not consider this post irrelevant... We are now 1087 in number (total members in our group). And that's a prime number... What is so interesting...
Could somebody please give me some online references to information about the benefits of sieving. E.g. Suppose a number K is a random integer then it has a 1...
As usual a typo on my formula! I know it was just an example but if K is not divisible by 2 or 3 then the chance of it being prime is 3/(lnK) Gary garychaffey2...
hi, ... Its a Kynea prime number with index 5? Sarad. ____________________________________________________ Sell on Yahoo! Auctions – no fees. Bid on great...
hi, The following observation might help. From 1-10, the numbers not divisible by 2,3 are 1,5,7. I.e 3 in number. Between 11-20,the numbers not divisible by...
Hi, I am a new member of primeform and as well primenumbers. I downloaded the pfgw source code version for win32. When I issue build command when opened in MS...
Can't think of anything off the top of my head, and David Wells's "Curious and Interesting Numbers" does not have an entry. According to Chris Caldwell's Prime...
Hello, New to the list and I've got a few questions about sieving Proth numbers in relation to the Sierpinski conjecture. I know Mikael Klasson and Paul...
