A A properly-colored perfect graph \((G, \sigma )\) on 8 vertices that is not an EDT graph. Next to the graph, the possible topologies of the species tree that are implied by the induced \(P_4\) according to Lemma 20 are shown. B A properly-colored cograph \((G',\sigma ')\) that is not an EDT graph. All possible assignments for the edges ac and ad are shown on the right-hand side together with the informative triples that they imply for the species tree according to Prop. 2. The assignment of the gray edges do not affect the respective triple
