Maximum number of edges in a planar graph I can delete this whole thing if you want to or not. I'm just happy I gut my answer and a comment from Noam Elkies who I allready knew about because he is well know in the math olympiad world. I can't see the close votes but if you want I'll gladly delete this. |
