numgens -- the number of generators

numgens X -- yields the number of generators used to present a module or ring.

For a polynomial ring or quotient of one, this is also the number of variables. For a free module, this is the same as the rank. For a general module presented as a subquotient, it is the number of columns in the matrix of generators.
