Using this seminal post from flouran as the basis I can now test Mersenne numbers for primeness exponentially faster than the ridiculously slow LL rubbish everyone is using now. And since, as is shown here by jasonp, the odds of failure are vanishingly small (<=25%), we only need to use a single base-2 Miller-Rabin test.
And not only that, I have discovered a lot of primes that you all have previously missed (proving that the LL test is complete rubbish). In fact, so far, every number I have tested has come up as prime. I have been so lucky to pick only prime yielding exponents that I should buy some lotto tickets. So boo-yah to whoever decided to use the LL test, nyah nyah nya nyah nyah. Base-2 Miller-Rabin rules. |

For all natural m>1 (2,3,4, ...) the following will always generate a Mersenne prime:
p=3*((2m-1)/3)^FLOOR((Sm-2 mod (2m-1)+2)/(Sm-2 mod (2m-1)+0.9)-1) where Sk is the familiar Mersenne test we all know (I shan't insult you all here by giving the formula, you already know it. ... Actually on second thought I will ...) S0 = 4 and for k > 0, Sk=Sk-12-2

[quote=;100935] You Lazy Bugger!!!!! You throw some snippets of already deduced information into the pool and hope Great Minds will create a Jason-Troels theorem that will allow you to predict the next 599+ Mersennes!!!! well I'm sorry I think it's totally - as Daffy said... Despicable!!!!!

I hereby declare that I have completed testing ALL exponents above 43112609 up to 1 trillion. And they are all prime! I hereby claim myself as the first discoverer for all these Mersenne numbers. Yay for me. So now it is up to all of you to go ahead and test them as double checks and you will see I am correct.
Now, if by chance you test some exponent and find it to be composite, well, umm, sorry about that, I guess my computer had a problem. Of course when you test an exponent and it comes up prime then remember that I found it first, you are only double checking. Please send my EFF prize cheque promptly, I badly need the money to buy lasers for my pet sharks. Thanks. PS: I don't care about split infinitives. So what. It was good enough for Star Trek.

A quack post forum? I'll try my best. I apologize to maths for this:
Hello, friends. I have discovered a BRAND NEW formula that generates ALL the prime numbers, and can factor any number! Of any size! Forget all that SIQS and GNFS nonsense! This revolutionary, groundbreaking new formula uses a quantum factor finding system, that can factor any number, in seconds! Here's proof!: Code:

Hello, friends. I have a REVOLUTIONARY new technology for finding MERSENNE PRIMES!
Stop using that LL garbage! That is outdated and USELESS! Try our revolutionary new method that uses consecutive division, to find super large Mersenne primes!! The divisions take place in a very very short time! Our machines use revolutionary quantum technology to test for numbers no one has ever dreamed of testing before.. And we have found a very large Mersenne prime! We have broken a record here!!! Here is our Mersenne prime: 23971024427881617784446989042698959305737250294982092756939591767576453404439030489955509227409721981924650383025441722461857496719966418363269236629669728139979470828471218304117361-1 is a prime number!! Here is our data: Code:
