Some arithmetic...
just asking things:
I'm guessing it's known that where 2n+1 =p; if so has anything useful come out of it ? Last fiddled with by science_man_88 on 20140714 at 23:13 Reason: took a +1 away after realizing the error.

Better than that, the Wieferich condition is equivalent to . This makes it slightly easier to test for the condition.
The only place I know of where the Wieferich condition is really useful is in the first case of Fermat's last theorem and in the solution to Catalan's conjecture.

Sorry for quoting this twice. One thing that just came to me is that this is equivalent of saying and this equals or which when you consider that if 2m+1 divides 2k+1, we can bring this down to or I'm I getting better or just making it worse ?

I certainly don't want to discourage you from pursuing these ideas, as not much progress has been made in understanding Wieferich primes! I would recommend reading the original paper of Wieferich, or possibly those that followed (I seem to remember one by Mirimanoff (sp?)), which introduced how these primes play a role in Fermat's last theorem. You may find a connection between what you are seeing and that problem.

nevermind I found a free preview of some of it and read a bit on wikipedia. I did fail so far to find specific n candidates that work, I'll give RDS that. edit: the part about sounds interesting for me since I see a way to generalize my first post to use those m. but I don't think it will help.

therefore the original congruence plus the basics of division can show that what I said is true. edit: this last result can be rewritten as Last fiddled with by science_man_88 on 20140728 at 22:13

potential proof ( partial checked for errors along the way)
I'd like a double check on this but based on my last congruence I believe I've found a way to prove p can not be the second prime in a twin prime pair. (Q,p)
I'd love your feedback since I feel like I'm talking to myself. Last fiddled with by science_man_88 on 20140730 at 19:39 Reason: forgot to attach the file the first time.
