In group theory, the term "core" can refer to a specific concept related to the notion of a normal subgroup. The core of a subgroup \\( H \\) of a group \\( G \\), often denoted as \\( \\text\{Core\}_G(H) \\), is defined as the largest normal subgroup of \\( G \\) that is contained within \\( H \\).
