Subgroup ($H$) information

Description:$C_6^2:C_2^2$
Order: \(144\)\(\medspace = 2^{4} \cdot 3^{2} \)
Index: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $\left(\begin{array}{rr} 0 & 5 \\ 17 & 0 \end{array}\right), \left(\begin{array}{rr} 9 & 0 \\ 0 & 25 \end{array}\right), \left(\begin{array}{rr} 1 & 14 \\ 14 & 1 \end{array}\right), \left(\begin{array}{rr} 13 & 0 \\ 0 & 13 \end{array}\right), \left(\begin{array}{rr} 15 & 14 \\ 0 & 15 \end{array}\right), \left(\begin{array}{rr} 9 & 0 \\ 0 & 9 \end{array}\right)$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_2\times C_6^2:D_{12}$
Order: \(1728\)\(\medspace = 2^{6} \cdot 3^{3} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Derived length:$3$

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

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 $W = N_G(H) / Z_G(H)$.

$\operatorname{Aut}(H)$ $C_2^5:D_6$, of order \(384\)\(\medspace = 2^{7} \cdot 3 \)
$\operatorname{res}(S)$$C_2^3\times D_6$, of order \(96\)\(\medspace = 2^{5} \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(16\)\(\medspace = 2^{4} \)
$W$$C_2\times D_6$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
