1.1. If a group satisfies the maximal condition for normal subgroups, then all its central factors are necessarily finitely generated. In [ 2 ], Hall asked whether there exist finitely generated soluble groups which do not satisfy the maximal condition for normal subgroups but all of whose central factors are …
