Popis:	Given a connected 2-complex X with fundamental group G, we show how ?3(X) may be computed as a module over Z[G]. Further, if X is a finite connected 2-complex with G(= ?1(X)) finite of odd order, then the stable class of ?3(X) is determined by G. In this case ?3(X) \otimes Q is free over Q[G]
