rehomogenizeIdeal -- rehomogenization of a the dehomogenized slack ideal
grassmannSectionIdeal -- given a slack matrix of a polytope, a cone or a matroid, or a set of polytope vertices, cone generators, or matroid vectors, and a set of set of hyperplane spanning set indices, it computes the Grassmannian section ideal corresponding to choice B of the object with slack matrix S
graphicIdeal -- creates the toric ideal of the non-incidence graph of a polytope
cycleIdeal -- constructs the cycle ideal of a realization
