Subgroup ($H$) information

Description:$S_3\times C_9$
Order: \(54\)\(\medspace = 2 \cdot 3^{3} \)
Index: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Exponent: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Generators: $\left(\begin{array}{rr} 1 & 9 \\ 0 & 1 \end{array}\right), \left(\begin{array}{rr} 1 & 8 \\ 6 & 13 \end{array}\right), \left(\begin{array}{rr} 1 & 12 \\ 0 & 1 \end{array}\right), \left(\begin{array}{rr} 10 & 9 \\ 9 & 1 \end{array}\right)$ Copy content Toggle raw display
Derived length: $2$

The subgroup is nonabelian, metacyclic (hence solvable, supersolvable, monomial, and 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: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Derived length:$3$

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

Automorphism information

While the subgroup $H$ is not characteristic, the stabilizer $S$ of $H$ in the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : S \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphisms $\operatorname{Inn}(G) \cap S$ is the Weyl group $W = N_G(H) / Z_G(H)$.

$\operatorname{Aut}(G)$$C_3^3.S_3^3$, of order \(5832\)\(\medspace = 2^{3} \cdot 3^{6} \)
$\operatorname{Aut}(H)$ $C_6\times S_3$, of order \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
$\operatorname{res}(S)$$C_6\times S_3$, of order \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(27\)\(\medspace = 3^{3} \)
$W$$C_6\times S_3$, of order \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
