Subgroup ($H$) information

Description:$C_3:D_{12}$
Order: \(72\)\(\medspace = 2^{3} \cdot 3^{2} \)

Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $\left(\begin{array}{rrrr} 1 & 0 & 3 & 0 \\ 5 & 1 & 4 & 3 \\ 0 & 0 & 10 & 0 \\ 4 & 0 & 6 & 10 \end{array}\right), \left(\begin{array}{rrrr} 1 & 1 & 7 & 6 \\ 4 & 7 & 0 & 7 \\ 8 & 3 & 4 & 10 \\ 8 & 8 & 7 & 10 \end{array}\right), \left(\begin{array}{rrrr} 0 & 6 & 5 & 3 \\ 3 & 10 & 8 & 4 \\ 6 & 5 & 9 & 10 \\ 9 & 5 & 7 & 2 \end{array}\right), \left(\begin{array}{rrrr} 2 & 8 & 1 & 4 \\ 10 & 6 & 0 & 1 \\ 9 & 2 & 4 & 3 \\ 9 & 9 & 1 & 8 \end{array}\right), \left(\begin{array}{rrrr} 10 & 0 & 0 & 0 \\ 0 & 10 & 0 & 0 \\ 0 & 0 & 10 & 0 \\ 0 & 0 & 0 & 10 \end{array}\right)$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $\SL(2,11):D_6$
Order: \(15840\)\(\medspace = 2^{5} \cdot 3^{2} \cdot 5 \cdot 11 \)
Exponent: \(660\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \cdot 11 \)
Derived length:$2$

The ambient group is nonabelian and nonsolvable.

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)$$(S_3\times D_4).\PSL(2,11).C_2$
$\operatorname{Aut}(H)$ $C_2^4.\SL(3,3)$, of order \(3456\)\(\medspace = 2^{7} \cdot 3^{3} \)
$W$$S_3\times D_6$, of order \(72\)\(\medspace = 2^{3} \cdot 3^{2} \)
