Uniqueness of an association scheme related to the Witt design on 11 points

Abstract

It follows from Delsarte theory that the Witt 44-(11,5,1)(11,5,1) design gives rise to a QQ-polynomial association scheme W\mathcal{W} defined on the set of its blocks. In this note we show that W\mathcal{W} is unique, i.e., defined up to isomorphism by its parameters.
