If and denote respectively the lower and upper central series of the group , an integer, and if is polycyclic (resp. polycyclic-by-finite) for some , then we prove that is polycyclic (resp. polycyclic-by-finite). The corresponding result with polycyclic replaced by finite was proved in 2009 by G.A. Fernández-Alcober and M. Morigi. We also present an alternative approach to the latter.
