Abstract: In this note we extend results on the covering graphs of modular lattices (Zelinka) and semimodular lattices (Gedeonova, Duffus and Rival) to the covering graph of certain graded lattices.

Keywords: covering graph, symmetric graph, centrally symmetric lattice, semimodular lattice, graded lattice, strong lattice
