A c-hybrid triple system is a decomposition of the complete v-vertex digraph into c cyclic tournaments of order 3 and [v(v-1)/3)-c] transitive tournaments of order 3. The authors determine the spectrum of v and c. They also show that every twofold triple system of order v underlies a c- hybrid system with \(c\geq 2v(v-1)/9\).
