Abstract
The Foulkes module \({H^{(a^b)}}\) is the permutation module for the symmetric group S ab given by the action of S ab on the collection of set partitions of a set of size ab into b sets each of size a. The main result of this paper is a sufficient condition for a simple \({\mathbb{C} S_{ab}}\) -module to have zero multiplicity in \({H^{(a^b)}}\) . A special case of this result implies that no Specht module labelled by a hook partition (ab − r, 1r) with r ≥ 1 appears in \({H^{(a^b)}}\) .
