Abstract. We study a representation of S, that is related to the shape of sets of
vectors in ~". We want to determine the invariants of this representation, and obtain
a complete description for the case of S,.
Keywords: Invariants of finite groups, Shape of sets of vectors.
1 Introduction
When studying the shape of a set of n vectors in W", we are led to consider the
