Subgroup ($H$) information

Description:$C_{10}.C_2^4$
Order: \(160\)\(\medspace = 2^{5} \cdot 5 \)
Index: \(990\)\(\medspace = 2 \cdot 3^{2} \cdot 5 \cdot 11 \)
Exponent: \(20\)\(\medspace = 2^{2} \cdot 5 \)
Generators: $\left(\begin{array}{rrrr} 4 & 4 & 2 & 6 \\ 10 & 9 & 1 & 2 \\ 5 & 3 & 2 & 7 \\ 4 & 5 & 1 & 7 \end{array}\right), \left(\begin{array}{rrrr} 9 & 9 & 8 & 10 \\ 3 & 8 & 0 & 8 \\ 6 & 5 & 3 & 2 \\ 6 & 6 & 8 & 2 \end{array}\right), \left(\begin{array}{rrrr} 9 & 0 & 0 & 0 \\ 0 & 9 & 0 & 0 \\ 0 & 0 & 9 & 0 \\ 0 & 0 & 0 & 9 \end{array}\right), \left(\begin{array}{rrrr} 7 & 7 & 3 & 0 \\ 5 & 4 & 0 & 8 \\ 2 & 0 & 4 & 7 \\ 0 & 9 & 5 & 7 \end{array}\right), \left(\begin{array}{rrrr} 3 & 3 & 6 & 0 \\ 6 & 8 & 0 & 5 \\ 7 & 0 & 8 & 3 \\ 0 & 4 & 6 & 3 \end{array}\right), \left(\begin{array}{rrrr} 10 & 0 & 0 & 0 \\ 0 & 10 & 0 & 0 \\ 0 & 0 & 10 & 0 \\ 0 & 0 & 0 & 10 \end{array}\right)$ 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 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$
$\operatorname{Aut}(H)$ $C_4\times S_4\wr C_2$, of order \(4608\)\(\medspace = 2^{9} \cdot 3^{2} \)
$W$$C_2^2\times D_4$, of order \(32\)\(\medspace = 2^{5} \)
