In this work, we study primary groups containing proper fully invariant subgroups isomorphic to the group, the so-called $IF$-groups. We define the admissible sequence of Ulm–Kaplansky invariants for primary groups. Using these sequences, $IF$-groups are described in some important classes of $p$-groups.
Mots-clés : $IF$-group, torsion complete group
Keywords: fully invariant subgroup, Ulm–Kaplansky invariants, admissible sequence.
