[QUOTE=literka;359572]OK. I will. Only that I will not answer to any abusive post.[/QUOTE]

That's perfectly fine.

Be comfortable in your own skin.

Be comfortable where you find yourself, and where you put yourself.

[QUOTE=BudgieJane;359530]I am amazed that so much has been written in this thread about the factorization of F7. Since you will have done this one a few years ago, with all the others you will have done in the meantime you should be looking at F77 now, or even F777, and certainly not F7.[/QUOTE]
In fact, far beyond that. Some of us already found factors for F1132, F9447, F17748, and F106432. And that's no joke. The factors are too large for the margins of this thread to contain. You can find them elsewhere. Some others found even larger factors (longer than 800,000 digits).

Certainly, some people will never believe that 30967*2^106436+1 divides 2[SUP]2[SUP]106432[/SUP][/SUP]+1. How can they? [I]There were computers involved![/I] Surely, it is a lie, isn't it?
-- No, it is not a lie, "and stop calling me Shirley". Furthermore, wrap you head around this: how can you be sure that 2[SUP]57,885,161[/SUP]-1 is prime? You can't, can you!

I hate to appeal to authority (in this case an authority of actually having done something before talking). But some people can only understand a direct illustration.

[QUOTE=literka;359560]These are hard questions to answer, especially to people, who don't know mathematics or to the people like you, who are convinced that something is worthless.[/QUOTE]

Did you see the part of my post where I indicated that I was not trying to imply anything with my questions? I really was trying to reserve judgment. When I asked the questions, I was not fully convinced that your work was worthless. But your response has sure moved me closer to that conclusion.

You forgot Paul Jobling, Jim Fougeron and Geoffrey Walter Reynolds. They all paid for it, too. And one George Woltman definitely chipped in a few drops of sweat, blood or something.

Two people A and B met. Mr, A has a house in mountains with no electricity and road leading to this house. Mr. A says "I have a valuable house". Mr. B says "this house is worthless. I would never live in this house".
The discussion who is right may lead only to a quarrel, since both are right and both are wrong in the same time.
As I said before: You may have your own opinion. I will respect your opinion, but don't press me any further, because I am convinced about one - the discussion would be worthless.

[QUOTE=literka;359569]I just don't want to be called crank ...[/QUOTE]

The crank is one of humankindâ€™s most useful inventions. It is defined as a right-angled arm attached to a rotating shaft that converts circular motion into reciprocal motion or vice versa.

Cranks are commonly found on treadle sewing machines, pencil sharpeners, fishing reels and internal combustion engines. Simple cranks were used by the Romans in hand mills and by the Greeks in Archimedes screws 2000 years ago.

Just remember that cranks make the world go around.

How are you getting on with F88?

Still I don't want to be a crank. The most I dislike it is this "reciprocal motion".

If I knew I would write another page. A new concept is required.
