This number was known to be prime in 1876, when they didn't have supercomputers. Even then there were much better techniques for testing primality than exhaustively checking divisibility. | ||

I didn't say for 2^127 -1 you need a super computer, this number is "relatively" small (~10^38). But for 2^(2^127-1) -1, show me how you can do it whitout a super computer, knowing that 2^127 -1 is prime. I really want to see that. edit : when i talked about super computer, i was talking about the next iterations. | ||

about the math problem, use induction (basic 1st year math) | ||

If you'd put all the computers in the world to work on this problem for the next 10 billion years, you wouldn't yet know if that number is really prime. Assuming it is prime. That's how big that number is. Math has many simple ways to tell the people that some questions will never get responses. | ||

Maybe one day, it will be possible, who knows. | ||

Anyway, my point is, why the hell would you use 'hi TL' on a TL? Just 'Hi!' would be enough in my opinion. There's no need for redundant stuff, especially one that shares some similarities with 4chan... | ||

There's no need for redundant stuff, especially one that shares some similarities with 4chan... Similarly, 4chan.org and teamliquid.net both have advertisements. I don't think teamliquid.net should have advertisements because 4chan.org has them. Also, 4chan.org has moderators, so I think the banlings should surrender their powers. 4chan is a website, so I think teamliquid should become a restaurant. Seriously. All he did was greet us, it's not the least bit rude. | ||

Assuming it is prime. That's how big that number is. Math has many simple ways to tell the people that some questions will never get responses. That assumes that checking divisibility is the only way to check this or even that our current methods for checking primality are the only ones. I agree that we won't find a solution to OP, but that does not mean that propositions here are the only way to get there. EDIT: by "we" I mean this thread/TL | ||
