All the known rational boundary states for Gepner models can be regarded aspermutation branes. On general grounds, one expects that topological branes inGepner models can be encoded as matrix factorisations of the correspondingLandau-Ginzburg potentials. In this paper we identify the matrix factorisationsassociated to arbitrary B-type permutation branes.
