Re: Four square theorem

Hi;

As far as I know this is a computational problem. You can get the number of solutions but to determine what they are you will need a computer.

For instance the number of solutions to



with



is 3744


To give you an idea of the complexity of the problem please go here;

In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.
