Here's an image that I made a long time ago. The important thing to notice is that there are no monochromatic triangles, that is, the edge colorings are "good". This can be done with 16 vertices (with 3 colors) in exactly two ways (as shown below), up to isomorphism, and cannot be done with 17 or more vertices, so the Classical Ramsey Number R(3,3,3)=17.
