We consider the cocircuit graph G M of an oriented matroid M, which is the 1-skeleton of the cell complex formed by the span of the cocircuits of M. As a result of Cordovil, Fukuda, and Guedes de Oliveira, the isomorphism class of M is not determined by G M , but it is determined if M is uniform and

In this paper, we prove that any simple and cosimple connected binary matroid has at least four connected hyperplanes. We further prove that each element in such a matroid is contained in at least two connected hyperplanes. Our main result generalizes a matroid result of Kelmans, and independently,

We introduce a splitting operation for binary matroids which is a natural generalization of the splitting operation for graphs and investigate some of its basic properties. Eulerian binary matroids are characterized in terms of the splitting operation.
