Subgroup ($H$) information

Description:$C_3\times S_3$
Order: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Index: \(162\)\(\medspace = 2 \cdot 3^{4} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $\langle(1,3,2)(4,5,6)(7,9,8)(10,11,12)(13,15,14)(16,17,18), (10,12,11)(13,14,15)(16,18,17), (1,17)(2,16)(3,18)(4,10)(5,11)(6,12)(7,14)(8,15)(9,13)\rangle$ 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: $C_3^4:S_3^2$
Order: \(2916\)\(\medspace = 2^{2} \cdot 3^{6} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
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)$$\He_3^2:(S_3\times D_4)$, of order \(34992\)\(\medspace = 2^{4} \cdot 3^{7} \)
$\operatorname{Aut}(H)$ $D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
$\operatorname{res}(S)$$D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(162\)\(\medspace = 2 \cdot 3^{4} \)
$W$$D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
