MaxDegree -- the maximum degree of a monomial to calculate

i1 : R = QQ[x,y]

o1 = R

o1 : PolynomialRing

i2 : I = ideal(x^2 - y^2)

            2    2
o2 = ideal(x  - y )

o2 : Ideal of R

i3 : getMons(R, I, MaxDegree=>15)
Ideal is not finite over the base (quotient ring has infinitely many monomials)
Monomials up to degree 15 given
