摘要

A graph obtained by deleting a Hamming code of length n = 2~r ?1 from a n-cube Q_n is called as a Hamming shell. It is well known that a Hamming shell is regular, vertextransitive, edge-transitive and distance preserving (Borges and Dejter in J Comb Math Comb Comput 20:161–173, 1996; Dejter in Discrete Math 124:55–66, 1994; J Comb Des 5:301–309, 1997;DiscreteMath 261:177–187, 2003). Moreover, it is Hamiltonian (Gregor and Skrekovski in Discrete Math Theor Comput Sci 11(1):187–200, 2009) and connected (Duckworth et al. in Appl Math Lett 14:801–804, 2001). In this paper, we prove that a Hamming shell is edge-bipancyclic and (n ? 1)-connected.
