In particular, it tells us that if graph G is ε-far from being triangle-free, then there is a (computable) constant δ = δ(ε) so that G has at least δn 3 triangles. Example (Triangle-freeness Testing Algorithm). Given graph G, choose a random set X of q(ε) = 1/δ triples of vertices independently at random, where δ is as above.
