Definition

A group $N$ is termed Frattini-embedded normal-realizable if there exists a group $G$ and an embedding of $N$ in $G$ such that $N$ is a Frattini-embedded normal subgroup of $G$. In other words, $N$ is a normal subgroup and $NH$ is a proper subgroup of $G$ for any proper subgroup $H$ of $G$.

Relation with other properties

Stronger properties

• Finite-Frattini-realizable group
• Finite-(Frattini-embedded normal)-realizable group

Weaker properties

• Inner-in-automorphism-Frattini group: This condition states that the inner automorphism group lies inside the Frattini subgroup of the automorphism group. For full proof, refer: Frattini-embedded normal-realizable implies inner-in-automorphism-Frattini
• ACIC-group: For full proof, refer: Frattini-embedded normal-realizable implies ACIC

Metaproperties

Subgroups

This group property is not subgroup-closed, viz., we can have a group satisfying the property, with a subgroup not satisfying the property

Quotients

This group property is not quotient-closed, viz., we could have a group with the property and a quotient group of that group that does not have the property

Characteristic subgroups

This group property is characteristic subgroup-closed: any characteristic subgroup of a group with the property, also has the property
