Abstract
In this paper a nonexistence theorem of Schützenberger of 1949 for symmetric designs is discussed.This result together with the theorems of Bruck-Ryser and Chowla-Ryser yield many nonexistence results for orbital matrices as well. In the second part, relations of orbital matrices to other combinatorial structures, e.g. weighing matrices, are discussed.
