| Abstract: | A subgroup  of a group  is said to be normal-by-finite if the core  of  in  has finite index in  . In this article groups satisfying the minimal condition on subgroups which are not normal-by-finite and groups with finitely many conjugacy classes of subgroups which are not normal-by-finite are characterized. |
