Let P (G, λ) be the chromatic polynomial of a graph G. Two graphs G and H are said to be chromatically euqivalent,then G is said to be chromatically unique.In this paper, we discuss a chromatically equivalent pair of graphs in one family of K4-homeomorphs, K4(1, 2, 8, d, e, f ).The obtained result can be extended in the study of chromatic equivalence classes of K4(1, 2, 8, d, e, f ) and chromatic uniqueness of K4-homeomorphs with girth 11.
