Chromatic classes of 2-connected (n, n + 4)-graphs with three triangles and one induced 4-cycle
For a graph G, let P (G, λ) be its chromatic polynomial. Two graphs G and H are chromatically equivalent, denoted G ∼ H, if P (G, λ) = P (H, λ). A graph G is chromatically unique if P (H, λ) = P (G, λ) implies that H ≅ G. In this paper, we shall determine all chromatic equivalence classes of 2-conne...
