Abstract
Super Weyl group plays an important role in the study of representations of basic classical Lie superalgebras. The Coxeter graphs for super Weyl groups of basis classical Lie superalgebras have been given in \cite{CLS}, where the authors also made a proposal on the Coxeter graphs for the super Weyl groups of exceptional classical Lie superalgebras , and . In this paper, we present all fundamental systems of the exceptional Lie superalgebras and get the Coxeter graphs for the corresponding super Weyl groups, verifying a proposal in \cite{CLS}.
