Abstract
The maximum number of cyclic triples in an oriented graph of a given order is well known, being realized by the regular and near-regular tournaments. We consider the the responding problem of determining the maximum number of cyclic triples in an oriented graph with a given number of arcs. A formula is found provided that the number of vertices is not too small relative to the number of arcs. (C) 2001 Academic Press.
