How do you define your polynomials? Are you sure that you *do* define
polynomials?
Examples:
1. This is a polynomial:
sage: R. = QQ[]
sage: p = x^2

i tried to take this into consideration
giving the following code
P. = PolynomialRing(QQ,order='neglex')
I = Ideal(x^5 + y^4 +z^3, x^3 + y^2 + z^2 -1)
print I
gb=I.groebner_basis()
rgb=Ideal(gb).interreduced_basis()
bgr=Ideal(rgb)
ir=Ideal(f.Im() for f in bgr)
print 'with revlex order'
print rgb
p

How do you define your polynomials? Are you sure that you *do* define
polynomials?
Examples:
1. This is a polynomial:
sage: R. = QQ[]
sage: p = x^2+3*x*y+y^3
sage: p.lm()
y^3
sage: type(p)
