【 摘 要 】

Two subgroups X and Y of a group G are said to be conditionally permutable in G if X permutes with Y-g for some element g E G. i.e., XYg is a subgroup of G. Using this permutability property new criteria for the product of finite supersoluble groups to be supersoluble are obtained and previous results are recovered. Also the behaviour of the supersoluble residual in products of finite groups is studied. (C) 2010 Elsevier Inc. All rights reserved.
