        "determinant"
        SYNTAX: X = det(A)

        A is a square matrix over Z, Q, Z/mZ, GF(p^n) (where p is a 
        prime), over a number field, over polymonials over these 
        structures or over rational functions.

        X is assigned the determinant of A.


        Example 1: (correct)

                det({{x, y} {x + 2, y^3}})


        Example 2: (incorrect)

                det({{x, y}})

_ERR_NR_074


        Example 3: (correct)

                det({{NF(A), y - 4, 2} {x, 3, 1/2} {-NF(A^2), 1, -4/3}})
