From: Archimedes Plutonium on 12 Jul 2010 18:35 Alright, I made a series of mistakes in the last several posts, starting off by thinking that the method that proves infinitude of Twin Primes is going to prove Quad Primes, then N+6 primes then etc etc. When caught in confusion, it is best to walk away from it and let the mind settle down, and piece things together. Most thoughts of complex things are thoughts in error, and only rarely are thoughts about complex things correct. I had a proof of the Infinitude of Twin Primes dating all the way back to 1993. When the Euclid Infinitude of Regular Primes is done in the Indirect Method, it actually is a proof, not of the Regular Primes, for which it easily can be, but is a proof of the Infinitude of Twin Primes. Because the very same mechanism that P+1 is necessarily prime in that method, allows for P-1 to be necessarily prime. Euclid INDIRECT Infinitude of Regular Primes proof: 1) Definition of prime 2) Hypothetical assumption, suppose set of primes 2,3,5,7,.. is finite with P_k the last and final prime 3) Multiply the lot and add 1 (Euclid's number) which I call W+1 4) W+1 is necessarily prime from the definition of prime and the assumption space 5) contradiction to P_k as the last and largest prime 6) set of primes is infinite. AP INDIRECT Infinitude of Twin Primes proof: (1) Definition of prime (2) Hypothetical assumption, suppose the set of primes 2,3,5,7,.. is finite with P_n and P_n+2 as the last and final two primes in existence (3) Multiply the lot and add 1 and subtract 1 (Euclid's numbers) which I will call W+1 and W-1 (4) W+1 and W-1 are necessarily two new primes from the definition of prime and from the assumption space (5) Contradiction to P_n+2 being the last and largest prime (6) Twin primes set is infinite Now I do not know if in the whole of mathematics, of all its proofs that the Infinitude of Primes proof yields a asymmetry of result in that the Direct method yields only a infinitude of regular primes and cannot produce infinitude of twin primes, whereas the Indirect method can yield both. So whether the Infinitude of Primes proof method of direct and indirect is the only asymmetrical example or whether mathematics has dozens of proofs where an asymmetry between direct and indirect exists. I would guess asymmetry abounds. Now my series of mistakes is all due to my stubborn wish that the Indirect method proves quad primes then N+6 primes etc etc. We can clearly see why that is not the case. We never needed the square root patch in indirect. What prevents a Quad Prime proof is that W+2 and W-2 are no longer guaranteed to be nondivisible by all the primes in the succession list S. We can no longer say that when dividing W+2 by all the primes that exist in S, leave a remainder. So all we get as a proof by Indirect Method is a Twin Prime proof. But that is sufficient to prove the infinitude of Quad primes and all primes of form N + 2k for k>1. I say this because to have only Regular Primes infinite and N +2 primes infinite but to have N+4, N+6, etc etc as all finite sets of primes is a contradiction. Whether a contradiction of the Prime distribution theorem or some other distribution of primes theorem I am not quite sure as yet. What I suspect is that given the information that Twin Primes is an infinite set, makes the proposition that all N+2k, k>1 sets of primes must also be infinite.
