摘要：
We classify the nilpotent finite groups G which are such that the unit group U(ZG) of the integral group ring ZG has a subgroup of finite index which is the direct product of noncyclic free groups. It is also shown that nilpotent finite groups having this property can be characterised by means of the Wedderburn decomposition of the rational group algebra QG. (C) 1996 Academic Press, Inc.
