It sounds unlikely to me, but it's not my field. How many natural numbers have you checked your formula for? Mobel is a number theorist on here who wishes to encourage creativity. I hope he has something useful to say on this. Last edited by skipjack; October 16th, 2016 at 01:57 AM.

Nooo. We can't start doing this.

I think we should ask the mods to fix the block function.

But I will leave it up to the experts here to verify or discount the formula.

How many primes numbers have you tested to verify that they are produced by produce natural numbers? What do you mean by $6(\infty)N-1$? The formula has three lines, can you explain how I generate a value for each line in order to combine them? Last edited by v8archie; October 16th, 2016 at 04:35 AM.

 October 17th, 2016, 05:49 AM #8 Newbie   Joined: Oct 2016 From: United States Posts: 3 Thanks: 0 It is probably not well written and organized, I agree. With the tables I have concocted, I have simply discovered that not only do all primes exist within the parameters of 6N±1 (after the numbers 2 and 3), but that all non primes within 6N±1 are simply all of the multiples of all of those numbers within 6N±1 (without exception). My formula is an attempt (albeit lame, perhaps) of showing that all primes are elicited by removing the sets of those multiples of 2, and 3, and 6N±1. If mine is not correctly written, surely one with greater expertise than mine can accomplish it.
