Webare no reflections in this action at all. We may decomposeV as V = U W,whereU and W are the subspaces de ned by X =0,andY =0, respectively. Then U and W each carry the natural reflection group action ofS n. From this point of view, the diagonal action of S n is a special case of the action of a reflection group W on the coordinate ring
