Abstract

The almost split sequences terminating in certain Knörr lattices for finite groups are shown to have indecomposable middle terms. The tree classes of the connected components of the stable Auslander-Reiten quiver containing certain Knörr lattices for elementary abelian $p$-groups are shown to be $A_\infty.$
