Abstract : In this paper the authors investigate some problems connected with selfdual closed classes and permutation groups. A typical problem in this direction is the following. Let G be a permutation group. What is the cardinality of closed classes contained in the centralizer of G? We review some earlier results and discuss the case of small permutation groups. Some open problems are formulated, too. (Author)
