I'd like to find all Graphs with 4 vertex that do not have an isomorph complementary graph.

Via drawing them, I found that all Graphs with Edges more than "4 over 2" / 2 do not have such an isomorph complementary graph.

Is this right?

"4 over2" / 2 is three. And the last Graph that has such a complem. isomorph graph has 3 edges.
