degreesRing n -- produce the ring in n variables whose monomials are to be used to represent degrees in another ring with multi-degrees of length n
degreesRing R -- produce the ring in n variables whose monomials are the degrees of elements of R.

Elements of this ring are used as Poincare polynomials for modules over R.

Note: the monomial ordering used in the degrees ring is RevLex, so the polynomials in it will be displayed with the smallest exponents first, because such polynomials are often used as Hilbert series.
