 Post subject: Number of variables in one polynomial.
PostPosted: Wed Mar 22, 2017 2:56 am 
This might sound as a trivial question, but it is not. Is there a command to check the number of variables in a polynomial? The situation is this:

I can add to the system as many equations as I wish, infinite. The problem is, they become more and more cumbersome. On the other hand, after that I manage to calculate the Gröbner basis, I take the "smallest" polynomial, and see how far I am by counting its variables. For huge polynomials this is no easy task.

Code:
size(variables(p));
