Description
The docstring of sage.rings.polynomial.multi_polynomial_libsingular.MPolynomial_libsingular.reduce() says:
INPUT: - ``I`` - a list/set of polynomials. If ``I`` is an ideal, the generators are used.
However:
sage: R.<x,y> = QQ[] sage: J = R.ideal(x^2 + y^2 - 1, 16*x^2*y^2 - 1) sage: (y^4).reduce(J.gens()) y^4 sage: (y^4).reduce(J) y^2 - 1/16
