- I don't like being told "never",but I have played with primes off and

on for years and found no pattern to them. I have recently discovered

that there is a constantly shifting pattern to the primes,themselves,

but there is a constant pattern to the composites. I am "selling" an

idea. If you are "buying", the "cost" is whatever time you expend to

disprove, approve, or otherwise play with it. No copyrite or patent

(pending or otherwise). I have only a basic understanding of algebra,

so please bear with me. I just barely undersand a+b=c. OK. The common

understanding and explenation. All primes, except 2 are odd. Yeah!

That just knocked half the numbers out of the game. Hey!! All numbers

ending in 5 can't be prime. Now my search is down to 12 out of 30

numbers. I think I can cut the search down to 8 out of 30. Let's kick

out the 3's. The way to do that is 3*x+y=possible prime(pp). If x=

(odd), then y=2. If x=(even) then y=1. Thus it starts:

3*1+2=5, prime; 3*2+1=7, prime; 3*3+2=11, prime; 3*4+1=13, prime;

3*5+2=17; prime; 3*6+1=19, prime; 3*7+2=23, prime; 3*8+1=25,

composite, 5*5. That worked prety good up to there, but can I predict

the next composite in the series? Let's see. 5*5+2*5=5*7=35. Carry

on. 3*9+2=29, prime; 3*10+1=31, prime; 3*11+2=35, composite, 5*7.

Ok so far. Now, to compute for the next two composites.

5*7+2*7=7*7=49 and 5*7+4*5=5*11=55. Move it on up. 3*12+1=37, prime;

3*13+2=41, prime; 3*14+1=43, prime; 3*15+2=47, prime; 3*16+1=49,

composite, 7*7; 3*17+2=53, prime; 3*18+1=55, composite,5*11. I

worked this up to 3*333+2=1001, but the floppy was corupted and I

lost all the info. I am working it again on floppy and hard drive for

back up. There are more patterns, but I don't think it will help in

the search for mega primes. Only a small bit of interesting, and

trivial, info. - http://www.primepuzzles.net/problems/prob_037.htm :)

I'm currently working on the same idea and over the last year i've found out several simple properties of these patterns; currently i'm preparing a written version to give a better tool to enable proves to these and further properties. i'll possibly release it within a month or two.

So far, it looks like you're, uh, "reinventing the wheel." :) Read this

earlier message and see if it's similar to what you're doing:

http://mindspring.com/~benbradley - Yes. Liu's prime formula is the first formula, which can prove

further properties of primes.

I wish that you may use the idea to get great success.

I try prove the prime k-tuple conjecture, had submited normal

journal, it is very hard to referee it.

Perhaps I will release a now version.
