Subgroup ($H$) information

Description:$C_5\times Q_8$
Order: \(40\)\(\medspace = 2^{3} \cdot 5 \)
Index: \(3960\)\(\medspace = 2^{3} \cdot 3^{2} \cdot 5 \cdot 11 \)
Exponent: \(20\)\(\medspace = 2^{2} \cdot 5 \)
Generators: $\left(\begin{array}{rrrr} 5 & 8 & 4 & 2 \\ 6 & 10 & 4 & 4 \\ 6 & 0 & 1 & 3 \\ 10 & 6 & 5 & 6 \end{array}\right), \left(\begin{array}{rrrr} 9 & 9 & 8 & 10 \\ 3 & 8 & 0 & 8 \\ 6 & 5 & 3 & 2 \\ 6 & 6 & 8 & 2 \end{array}\right), \left(\begin{array}{rrrr} 9 & 0 & 0 & 0 \\ 0 & 9 & 0 & 0 \\ 0 & 0 & 9 & 0 \\ 0 & 0 & 0 & 9 \end{array}\right), \left(\begin{array}{rrrr} 10 & 0 & 0 & 0 \\ 0 & 10 & 0 & 0 \\ 0 & 0 & 10 & 0 \\ 0 & 0 & 0 & 10 \end{array}\right)$ Copy content Toggle raw display
Nilpotency class: $2$
Derived length: $2$

The subgroup is nonabelian, elementary for $p = 2$ (hence nilpotent, solvable, supersolvable, monomial, and hyperelementary), and metacyclic (hence metabelian).

Ambient group ($G$) information

Description: $\GL(2,11):D_6$
Order: \(158400\)\(\medspace = 2^{6} \cdot 3^{2} \cdot 5^{2} \cdot 11 \)
Exponent: \(1320\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \cdot 11 \)
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)$$(C_2\times C_6).C_2^5.\PSL(2,11).C_2$
$\operatorname{Aut}(H)$ $C_4\times S_4$, of order \(96\)\(\medspace = 2^{5} \cdot 3 \)
$W$$C_2^2$, of order \(4\)\(\medspace = 2^{2} \)
