What's this??? :question:[URL="http://www.bearnol.pwp.blueyonder.co.uk/Math/mmprime.html"]:exclaim:[/URL]

It's talking about 2, 3, 7, 127, M127, MM127, MMM127, ... are all primes!!!

More info see [url=http://www.mersenneforum.org/showthread.php?t=10732&highlight=MM31]here[/url].

Is that a joke? Or that's real?

If that's real, why didn't that got on the top 5000 list?

[QUOTE=Merfighters;217215]Is that a joke?[/QUOTE]
I wouldn't say it's likely to be a joke. More likely to be someone with little mathematical skills, producing very flawed mathematics and so false results, but who is sure of himself anyway. These results are usually the answers (or so they think) to long-sought-after problems, like this one (supposedly) producing infinite primes and infinite Mersenne primes through an impossibly easy method. People like that, we like to call: cranks. :crank:
For example, he claims to have shown that there's an infinite number of Mersenne primes (which is currently not known despite work by real mathematicians) using this as proof:
[QUOTE]hcf (Mp, n) = 1, for all n<p [by Lemma 1]

let p->99999… [Euclid]

=> Mp prime

=> there exist an infinite number of prime Mp[/QUOTE]Besides the confusing and non-mathematical notations, he does not explain what exactly 99999... is, how it related to Euclid, or how that makes Mp prime. Then by unproven inductions and more nonsensical handwaving, he says:
[QUOTE]3) Induce to show inf. no. multiple-mersenne primes, .....MMp
4) Apply probabilistic argument to deduce p=2
5) Use Mp prime => p prime to show ALL .....MMM2 prime[/QUOTE]And he doesn't say anything suggesting 2 is special, so the same thing should work for every Mersenne prime, huh? But [URL="http://factordb.com/search.php?query=MM13"]MM13[/URL] is composite.

[/quote]The Internet allows anyone who doesn't really understand mathematics to proclaim false statements to the world.

Aha, so the Prime World was not broken up. :smile::smile:
