# Central implies potentially fully invariant in finite

From Groupprops

This article gives the statement and possibly, proof, of an implication relation between two subgroup properties, when the big group is a finite group. That is, it states that in a Finite group (?), every subgroup satisfying the first subgroup property (i.e., Central subgroup (?)) must also satisfy the second subgroup property (i.e., Potentially fully invariant subgroup (?)). In other words, every central subgroup of finite group is a potentially fully invariant subgroup of finite group.

That is, it states that in a Finite group (?), every subgroup satisfying the first subgroup property (i.e., Central subgroup (?)) must also satisfy the second subgroup property (i.e., Finite-potentially fully invariant subgroup (?)). In other words, every central subgroup of finite group is a finite-potentially fully invariant subgroup of finite group.
