Jakubik has shown that for discrete modular lattices all graph isomorphisms are given by certain direct product decompositions. Duffus and Rival have proved a similar theorem for graded lattices which are atomistic and coatomistic. Modifying some of the results of Duffus and Rival we give a common g
