If L is a lattice, the automorphism group of L is denoted Aut(L). It is known that given a finite abstract group H, there exists a finite distributive lattice D such that Aut(D) £= H. It is also known that one cannot expect to find a finite orthocomplemented distributive (Boolean) lattice B such that Aut(B) s= H. In this paper it is shown that there does… (More)

The geometric duals of the generalized Petersen graphs G(n, k) are the Greechie representations of the Generalizations of Gsz. The duals are denotes by G*(n, k) and the generalizations by L(G*(n, k)). For these generalizations which are orthomodular posets and lattices, the automorphism groups are completely determined. State properties are also… (More)
