Matroids and Semimodular Lattices,ar lattices and seeing how they are related to the symmetric group. We develop a viewpoint of a semimodular lattice as a chamber system with a kind of metric that gives it a structure only slightly weaker than that of a building over .. This leads to a natural way to represent flag matroids in semim

Symplectic Matroids,r group, namely, .. the hyperoctahedral group. The resulting structures are called symplectic matroids, and they are in some sense rather general Coxeter matroids, as they include ordinary matroids and a third type, orthogonal matroids, as special cases. This will also prepare us to tackle Coxeter m
