Generalizing some results of P.Erdősand some of L.Moserand J. W.Moonwe give lower bounds on the number of completep-graphsKpof graphs in terms of the numbers of vertices and edges. Further, for some values ofnandEwe give a complete characterization of the extremal graphs, i. e. the graphsSofnvertices andEedges having minimum number ofKp’s.Our results contain the proof of the longstanding conjecture of P.Erdősthat a graphGnwith [n2/4] +kedges contains at leasttriangles ifk<n/2.
