A base of the cycle space of a binary matroid M on E is said to be convex if its elements can be totally ordered in such a way that for every e E E tk set of elements of the base containing e is an interval. \'Ure show that a binary matroid is cographic iff it has a convex base of cycles; equivalent
A graph is antipodal if, for every vertex c', there exists exactly one vertex V which is not closer to r than every vertex adjacent to 6. In this paper we consider the problem of characterizing tope graphs of oriented matroids, which constitute a broad class of antipodal graphs. One of the results i
