There's also a simpler, weaker construction in a similar spirit to the Mycielskian which lets us find a graph with χ ( G) = r, and ω ( G) < r (note the Mycielskian gives ω ( G) = 3 ). For r = 3, the cycle on five vertices works, and then simply add vertices which are connected to all existing vertices by induction to give a ... Webnumber of vertices in a graph, e = E to denote the number of edges in a graph, and f to denote its number of faces. Using these symbols, Euler’s showed that for any connected planar graph, the following relationship holds: v e+f =2. (47) In the graph above in Figure 17, v = 23, e = 30, and f = 9, if we remember to count the outside face.
