Just putting this out there for consideration...

Might you give us your name?

Apologies for the alphabet soup and the nomenclature....it's par for the course in any relatively small group of people working on the same or closely related technical things. As for not winning awards, the interface works well enough, and is similar enough to lots of other forums I have used. The people here who could change the interface have a lot of other, more important things to do with their time.

**************
see http://www.mersenne.org/various/math.php
and scroll down for an explanation of P-1 factoring.

How long would "It's about prime" take to factor M1061, incidentally?

Oh, and moderators:
A short note as to the problem with my previous post and the explanation of P-1 would be my idea of properly editing it.

Understood, but I was referring to the Mersenne.org site, which has "accumulated" (and that's being nice about it ) a fair amount of info over the years which could be organized better.

Somewhere between when the Andromeda Galaxy starts colliding with the Milky Way and when our own sun starts to burn out

It was nothing more than a clever RAM-resident trial division Prime solver that was able to handle 64-bit ints before any other Mac program. Mostly used as a benchmark by those who were confused by the preponderance of Macs spawned during the Guy Amelio era.

Featuring "amazing" optimizations such as adding +2, +2, +2, then +4 to candidate primes using a circular linked list after pre-loading 2, 3, 5, and 7 as the seed entries. That way, it would never generate a candidate prime that ended in 5.

You might laugh, but no Mac programs would do such things before it, and they were all constrained to 30 bits or less since Apple used the upper 2-bits of memory for "Handle states" in their Memory Manager ROM routines.

I also used a memory paging buffer for those with < 4 MB (not GB!) of RAM.

Those were the days.

yeah no offense I'd rather not look at something from a infiniteloop.com infinite loops means bad programming last I checked.

I can tell you what it used to say at www.7427466391.com


Congratulations. You've made it to level 2. Go to www.Linux.org and enter Bobsyouruncle as the login and the answer to this equation as the password.

This particular conversation is over.

I know who I am and who I worked for and what my stock portfolio is worth today.

And I don't have to answer to the likes of people such as yourself.

1. It was InfiniteLoop.org (not .com) so pay closer attention to details.
2. Apple Computer's Address was "1 Infinite Loop Way" at one point, and this company was a homage to that.
3. EVERY program ALWAYS executes an infinite loop while it runs. Usually in the form of "While(1)" in the old Pascal/C days when you created a busy Event Loop.
4. The name is a double-entendre for the exact same reason you mentioned. Most people THINK it's bad, while those who actually know, understand the underlying meaning.

Thanks for demonstrating which class you belonged to (and yet another double-entendre to the object oriented programmers out there, or will you enlighten us further with your explanation of OOPS?)

Another bit of nonsense from someone who refuses to study this
subject. The factors of 2^p + 1 are also of the form 2kp+1.
The "-1" in 2^p-1 is irrelevant.

The "-1" in P-1 has almost nothing to do with the "-1" in 2^p-1.

The "-1" in P-1 has everything to do with the fact that the group order
of Z/pZ* is p-1.

Too many ignorant posters who prattle about mathematics and fail to
understand that math is all about nitpicking. Getting the minute details
right is fundamental to the subject. Too many people who have spewed nonsense for years and who refuse to read.

anyways I forgot this was a thread for predicting Mersenne prime 48. part of my problem is even if I do read something I'm stupid enough to misinterpret it.

Can someone multiply this guy by (1 + i^2) already?
