Let t ( e) be the maximum number of triangles in a graph with e edges. We want t ( e) ∈ O ( e 1.5). As you may know, if e = ( k 2) for some k, the graph with the most triangles is the complete graph on k vertices, which has O ( e 1.5) triangles. So we can say there is a c such that t ( e) ≤ c e 1.5 whenever e = ( k 2) for some k.
