Alex, I think naïvely that a jury will do the difference between a result obtained by a logic method (with proof) and a result obtained by a random method (qui s'en remet au seul hasard). Is'nt true ?
Alain

They certainly will. From everything I have seen so far, your method is purely random.

It may not *be* random, but certainly seems "no better than random."

[QUOTE=Uncwilly;105721]An update:
3) finish with an odd number (other than 5)
3.5) check and make sure that the number is being tested.

I stand corrected :blush: :blush: , it seems like my algortim will fail in 1 out of 5 :grin:

No, only my process of reading seems to be "random". But it comes from the difficulties to applicate rules that are not "hasardeuses".
For example, the interval I have given in my last post is real. You can calculate it easily. Idem, I can propose such an interval for all the mersenne's numbers of the list, from the beginning.
Alain

Just post the damn method! If it's even possible that it could get rid of possible candidates, someone will say so.

Alain,
Either you post your method or you buy some computers and use them and your method to find M45.
Tony

OK
 

OK, I'am a little tired.
You can consult the famous method (for some hours) at this address :

I avise George Woltman of this post

I am waiting your reactions

Alain

Sorry if this approach prove to be wrong.

Proth-Gilbreath's conjecture
 

OK. Why not.
Here are some references for the Proth-Gilbreath's conjecture:

[URL="http://primes.utm.edu/glossary/page.php?sort=GilbreathsConjecture"]PrimeGlossary[/URL]
You have a method for computing, but I see no explaination about why this calculus should give the exponent of M45 ...
Too late now. I'll see tomorrow.

T.

Umm... are you trying to invert Gilbreath's conjecture by starting with a list of absolute differences of all 1s, then adding them up in different ways hoping that a prime appears after 45 steps? And even if a prime appears, what is there to suggest that that is the exponent of the 45th Mersenne prime? However, I can't say I really understand the explanation on your web page. Can you give a small example, step by step, how your method can be used to discover the 13th Mersenne prime, M521?
