Given a linear spaceLin affine space, we study its closurein the product of projective lines. We show that the degree, multigraded Betti numbers, defining equations, and universal Gröbner basis of its defining idealare all combinatorially determined by the matroidMofL. We also prove thatand all of its initial ideals are Cohen–Macaulay with the same Betti numbers, and can be used to compute theh-vector ofM. This varietyalso gives rise to two new objects with interesting properties: thecocircuit polytopeand theexternal activity complexof a matroid.
