On some polycyclic groups with small Hirsch length II
Abstract
A polycyclic group GG is called a NAFQn-group (AFQn-group) if every normal abelian subgroup (abelian subgroup) of any finite quotient of G is generated by n, or fewer, elements and n is the least integer with this property. In this paper, we describe the structures of NAFQ3-groups and AFQ3-groups, and bound the number of generators of AFQ3-groups and the derived lengths of NAFQ3-groups, which is a continuation of [H. G. Liu, F. Zhou and T. Xu, On some polycyclic groups with small Hirsch length, J. Algebra Appl. 16(11) (2017) 17502371–175023710].
