The concept of a combinatorial W P U -geometry for a Coxeter group W , a subset P of its generating involutions and a subgroup U of W with P βŠ† U yields the combinatorial foundation for a unified treatment of the representation theories of matroids and of even -matroids. The concept of a W P -matroid

We introduce the concept of depth and r-depth of a matroid M, proving that the sequence of the r-depths is the conjugate partition of the rank partition of M. The notion of quasitransversal is defined and its properties stated. We also present connections between the concept of r-depth, the quasi-tr
