Question

88:
In a cyclic graph of 15 vertices,
C15, the chromatic number
x(C15) =​

Answer 1

Answer:

3 is the chromatic number of vertices, edges, girth, and automorphisms are odd. Otherwise, 2 will be the chromatic number

Step-by-step explanation:

If several vertices in the cycle graph are even, then its chromatic number = 2.

If several vertices in the cycle graph are odd, then its chromatic number = 3.
