Subgroup ($H$) information

Description:$C_3^4$
Order: \(81\)\(\medspace = 3^{4} \)
Index: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Exponent: \(3\)
Generators: $\left(\begin{array}{rrrr} 0 & 0 & 1 & 0 \\ 0 & 1 & 0 & 0 \\ 2 & 0 & 2 & 0 \\ 1 & 0 & 2 & 1 \end{array}\right), \left(\begin{array}{rrrr} 1 & 0 & 0 & 0 \\ 1 & 1 & 2 & 0 \\ 0 & 0 & 1 & 0 \\ 1 & 0 & 2 & 1 \end{array}\right), \left(\begin{array}{rrrr} 1 & 2 & 1 & 1 \\ 0 & 1 & 0 & 0 \\ 0 & 2 & 2 & 1 \\ 0 & 1 & 2 & 0 \end{array}\right), \left(\begin{array}{rrrr} 1 & 0 & 0 & 0 \\ 0 & 2 & 2 & 2 \\ 0 & 0 & 1 & 0 \\ 0 & 1 & 2 & 0 \end{array}\right)$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is characteristic (hence normal), a semidirect factor, abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), and a $p$-group (hence elementary and hyperelementary).

Ambient group ($G$) information

Description: $C_3^3:S_3^2$
Order: \(972\)\(\medspace = 2^{2} \cdot 3^{5} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Derived length:$3$

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

Quotient group ($Q$) structure

Description: $D_6$
Order: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Automorphism Group: $D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
Outer Automorphisms: $C_2$, of order \(2\)
Nilpotency class: $-1$
Derived length: $2$

The quotient is nonabelian, metacyclic (hence solvable, supersolvable, monomial, and metabelian), hyperelementary for $p = 2$, an A-group, 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)$$\He_3^2:(S_3\times D_4)$, of order \(34992\)\(\medspace = 2^{4} \cdot 3^{7} \)
$\operatorname{Aut}(H)$ $C_2.\PSL(4,3).C_2$, of order \(24261120\)\(\medspace = 2^{9} \cdot 3^{6} \cdot 5 \cdot 13 \)
$\operatorname{res}(\operatorname{Aut}(G))$$D_6:S_3^2$, of order \(432\)\(\medspace = 2^{4} \cdot 3^{3} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(81\)\(\medspace = 3^{4} \)
$W$$D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
