Abstract

A class of groups is said to be countably recognizable if a group belongs to  whenever all its countable subgroups lie in . It is proved here that most of the relevant group classes of generalized nilpotent groups are countably recognizable. Moreover, some further countably recognizable group classes are exhibited.
