Re: no. of divisers

Hi bobbym

I think we should stop chatting because it is abother persons thread, and also, we have already reached that magical point where I have no idea what you are talking about.

The limit operator is just an excuse for doing something you know you can't.

Re: no. of divisers


I know of nothing better than computing the divisors and then checking mod 4 for each one.

I have been researching the problem for something else but have not found anything.

Just finished reading 8 books on number theory, found 3 new was to compute the Jacobi symbol but did not find a shortcut for yours.

In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
