Abstract
The set of special representations of a Weyl group has a natural graph structure: two special representations are joined by an edge if the corresponding special unipotent classes are consecutive for the partial order of special unipotent classes induced by the partial order on all unipotent classes. In this paper we prove a symmetry property of this graph.
