Index: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $\left(\begin{array}{rrrr} 0 & 0 & 1 & 0 \\ 0 & 1 & 0 & 0 \\ 2 & 0 & 2 & 0 \\ 1 & 0 & 2 & 1 \end{array}\right), \left(\begin{array}{rrrr} 2 & 0 & 0 & 0 \\ 0 & 1 & 0 & 0 \\ 1 & 0 & 1 & 0 \\ 2 & 0 & 0 & 1 \end{array}\right), \left(\begin{array}{rrrr} 1 & 2 & 1 & 1 \\ 0 & 1 & 0 & 0 \\ 0 & 2 & 2 & 1 \\ 0 & 1 & 2 & 0 \end{array}\right), \left(\begin{array}{rrrr} 1 & 0 & 0 & 0 \\ 0 & 2 & 2 & 2 \\ 0 & 0 & 1 & 0 \\ 0 & 1 & 2 & 0 \end{array}\right)$ Copy content Toggle raw display
Derived length: $2$

The subgroup is characteristic (hence normal), nonabelian, supersolvable (hence solvable and monomial), metabelian, and an A-group.

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: $C_3:S_3$
Order: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Automorphism Group: $C_3^2:\GL(2,3)$, of order \(432\)\(\medspace = 2^{4} \cdot 3^{3} \)
Outer Automorphisms: $S_4$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
Derived length: $2$

The quotient is nonabelian, supersolvable (hence solvable and monomial), metabelian, 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)$$C_3^2.S_3^3$, of order \(1944\)\(\medspace = 2^{3} \cdot 3^{5} \)
$\operatorname{Aut}(H)$ $C_2\times C_3^2:\GL(2,3)$, of order \(864\)\(\medspace = 2^{5} \cdot 3^{3} \)
$\operatorname{res}(\operatorname{Aut}(G))$$C_6.S_3^2$, of order \(216\)\(\medspace = 2^{3} \cdot 3^{3} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(9\)\(\medspace = 3^{2} \)
$W$$C_3^2:D_6$, of order \(108\)\(\medspace = 2^{2} \cdot 3^{3} \)
