degree

degree X -- returns the degree of a polynomial, vector, matrix, monomial, or module.

The degree may be an integer, or a vector of integers. The length of that vector is referred to as the 'number of degrees', and is provided by degreeLength.

The degree of a module of finite length is the same as its length.
     i6 = degree cokernel symmetricPower ( 2, vars R )
