Comment (by SimonKing):
PS: Adding a generator `fields` in our boolean polynomial ring, we get
{{{
sage: P.<magma, additive_magma, ring, field, distributive, finite,
division, commutative> = BooleanPolynomialRing()
sage: R = P*[field-ring*division*commutative, ring*division*finite-
ring*division*commutative*finite, ring-magma*additive_magma*distributive]
sage:
(magma*additive_magma*distributive*finite*division).reduce(R.groebner_basis())
field*finite
sage: (ring*commutative*finite*division).reduce(R.groebner_basis())
field*finite
}}}
