Question
What is the chromatic index of each of the Platonic graphs?
Step 1
Tetrahedral graph (3-simplex): This graph has 4 vertices and 6 edges. It is a complete graph (K4) with every vertex connected to every other vertex. The chromatic index of a complete graph K_n is n if n is odd, and n-1 if n is even. In this case, n=4, so the Show more…
