Subgroup ($H$) information

Description:$C_2\times D_6$
Order: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Index: \(72\)\(\medspace = 2^{3} \cdot 3^{2} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $\left(\begin{array}{rr} 23 & 0 \\ 0 & 1 \end{array}\right), \left(\begin{array}{rr} 1 & 33 \\ 0 & 1 \end{array}\right), \left(\begin{array}{rr} 23 & 0 \\ 0 & 23 \end{array}\right), \left(\begin{array}{rr} 1 & 33 \\ 33 & 34 \end{array}\right)$ Copy content Toggle raw display
Derived length: $2$

The subgroup is nonabelian, supersolvable (hence solvable and monomial), hyperelementary for $p = 2$, metabelian, an A-group, and rational.

Ambient group ($G$) information

Description: $C_{12}:D_6^2$
Order: \(1728\)\(\medspace = 2^{6} \cdot 3^{3} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Derived length:$2$

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

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_3^4:(S_3\times D_{12})$, of order \(442368\)\(\medspace = 2^{14} \cdot 3^{3} \)
$\operatorname{Aut}(H)$ $S_3\times S_4$, of order \(144\)\(\medspace = 2^{4} \cdot 3^{2} \)
$\card{W}$\(6\)\(\medspace = 2 \cdot 3 \)
