Derived length: $3$

The subgroup is characteristic (hence normal), maximal, a semidirect factor, nonabelian, and supersolvable (hence solvable and monomial).

Ambient group ($G$) information

Description: $C_3^3.S_3^2$
Order: \(972\)\(\medspace = 2^{2} \cdot 3^{5} \)
Exponent: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Derived length:$3$

The ambient group is nonabelian and supersolvable (hence solvable and monomial).

Quotient group ($Q$) structure

Description: $C_2$
Order: \(2\)
Exponent: \(2\)
Automorphism Group: $C_1$, of order $1$
Outer Automorphisms: $C_1$, of order $1$
Derived length: $1$

The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), a $p$-group, simple, and rational.

Automorphism information

Since the subgroup $H$ is characteristic, the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : \operatorname{Aut}(G) \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphism group $\operatorname{Inn}(G)$ is the Weyl group $W = G / Z_G(H)$.

$\operatorname{Aut}(G)$$C_3^3.S_3^2$, of order \(972\)\(\medspace = 2^{2} \cdot 3^{5} \)
$\operatorname{Aut}(H)$ $C_3^4:S_3^2$, of order \(2916\)\(\medspace = 2^{2} \cdot 3^{6} \)
$\operatorname{res}(\operatorname{Aut}(G))$$C_3^3:D_6$, of order \(324\)\(\medspace = 2^{2} \cdot 3^{4} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(3\)
