We prove the following characterization theorem: If any three of the following four matroid invariants-the number of points, the number of lines, the coefficient of λ n-2 in the characteristic polynomial, and the number of three-element dependent sets-of a rank-n combinatorial geometry (or simple ma

In this paper, we show that the full algebraic combinatorial geometry is not a projective geometry, it is only semimodular, but the p-polynomial points give a projective subgeometry. Also, we show that the subgeometry can be coordinatized by a skew field, which is quotient ring of an Ore domain. As
