Description changed by jdemeyer:

Old description:

> Writing an integer as sum of N squares.
>
> There are various questions:
> - Is it possible to write an integer ''n'' as a sum of ''k'' squares?
> - What is the number of ways in which one can do this?
> - Find a solution if there exists one.

New description:

 Writing an integer as sum of k squares.

 This ticket will:
 - add a Sage implementation of writing a number as a sum of 2 squares
 - add a Sage implementation of writing a number as a sum of 3 squares
 - add a Sage implementation of writing a number as a sum of k squares for
 any k >= 4
