Abstract :
For a graph G, let P(G; λ) denote the chromatic polynomial of G. Two graphs G and H arechromatically equivalent if they share the same chromatic polynomial. A graph G is chromaticallyunique if for any graph chromatically equivalent to G is isomorphic to G. In this paper, thechromatically unique of a new family of 6-bridge graph θ(a; a; a; b; b; c) where 2 ≤ a ≤ b ≤ c isinvestigated.
