In this paper, a configuration with n = (g) points in the plane is described. This configuration, as a matroid, is a Desargues configuration if d = 5, and the union of (~) such configurations if d > 5. As an oriented matroid, it is a rank 3 truncation of the directed complete graph on d vertices. Fr

We describe some of the properties of the pure braid groups of surfaces di erent from S 2 and RP 2 . In the case of compact, connected, orientable surfaces without boundary and of genus at least two, we give a necessary and su cient condition for the splitting of the pure braid group exact sequence
