Abstract:Two graphs are defined to be adjointly equivalent if and only if their complements are chromatically equivalent. Using the properties of the adjoint polynomials and the fourth character $R_4(G)$, the adjoint equivalence class of graph $B_{n-8,1,4}$ is determined. According to the relations between adjoint polynomial and chromatic polynomial, we also simultaneously determine the chromatic equivalence class of $overline{B_{n-8,1,4}}$ that is the complement of $B_{n-8,1,4}$.
Keywords:chromatic equivalence class   adjoint polynomial   the smallest real root   the fourth character.
