LetGbe a finite group,Qap-subgroup ofGandPa Sylowp-subgroup ofLetbe a complete discrete valuation ring of characteristic zero with residue class fieldof characteristicp> 0. Suppose that the group ringis of infinite representation type andis sufficiently large. Letbe a stable Auslander-Reiten component containing a Scott-latticeS(Q) with vertexQ. Then all the-lattices inhavePas their vertices. Also, we show that there exists an indecomposable-latticeLwith vertexPsuch that akG-moduleisQ-projective.Communicated by J. Zhang
