I think that's a very dangerous statement, as the boolean polynomial
ring is a *quotient* of the above polynomial
In other words, either use BooleanPolynomialRing without
specifying GF(2), or use PolynomialRing and specify GF(2).
If you set
sage: xxz = ['x%d'%(i) for i in range(1, 49)] + ['Z']
you have the choice between the following:
sage: V = PolynomialRing(GF(2), 49, xxz)
sage: V
Multiv
What is your point? Remove GF(2) as this is over GF(2) by default.
