Mersenne Prime Sequence
Could someone please check the attached theorem for errors and post a reply for the location of any errors?Mersenne Primes.pdf

I expect that you will notice the gaps (if you have not done so already) when you try to improve the written reasoning at those points.

Stan,
Could you please explain how your proof path would differ for a similar sequence: n_{0} = 2^51 (prime) n_{1} = 2^n_{0}1 (prime) n_{2} = 2^n_{1}1 (composite, has known factors) What is the specific reason that we wouldn't be able to plug it in the same proof and demonstrate that n_{2} is actually prime?

phi(2^51) does not divide phi(2^n_{0}1), therefore no sequence. My proof relies on the chain: phi(2^n_{0}1)  phi(2^n_{1}1)  phi(2^n_{2}1) etc. Last fiddled with by Stan on 20120121 at 12:35

Mersenne Primes
I believe the proof of my theorem to be now complete but I still need it checking. Any comments would be appreciated.Mersenne Primes.pdf

n_{0} = 19 (prime)
n_{1} = 2^n_{0}1 (prime) n_{2} = 2^n_{1}1 (?composite?)
