Abstract:	In this paper we study [3 -pairs of symmetric group algebras and their 'intermediate' block in detail. The aim is to understand how one block of a [3 : 2]-pair can inherit two properties - the Ext-quiver being bipartite and the principal indecomposable modules having a common Loewy length 7 - From the other. We establish some sufficient conditions for this inheritance, and verify these conditions for some special blocks. © 2005 Elsevier Inc. All rights reserved.
