Competition and phylogeny numbers are important parts of the competition and phylogeny graphs research.In this paper,we study the competition and phylogeny numbers for a class of graphs,in which each graph includes a clique and any triangle of the graph is included in this clique.These generalize some results of Kim,Robert sand Sheng.
