Un groupe est emboîté si les centres des caractères irréductibles forment une chaîne. Dans cet article, nous montrerons qu’il existe un ensemble de sous-groupes associés aux classes de conjugaison de groupe tel qu’un groupe est emboîté si et seulement si ces sous-groupes forment une chaîne.

A group is nested if the centers of the irreducible characters form a chain. In this paper, we will show that there is a set of subgroups associated with the conjugacy classes of group so that a group is nested if and only if these subgroups form a chain.
