Subgroup ($H$) information

Description:$\He_{11}$
Order: \(1331\)\(\medspace = 11^{3} \)
Index: \(55\)\(\medspace = 5 \cdot 11 \)
Exponent: \(11\)
Generators: $\left(\begin{array}{rrrr} 3 & 8 & 7 & 6 \\ 6 & 3 & 10 & 7 \\ 1 & 4 & 10 & 3 \\ 3 & 1 & 5 & 10 \end{array}\right), \left(\begin{array}{rrrr} 1 & 8 & 0 & 6 \\ 5 & 1 & 1 & 0 \\ 0 & 4 & 1 & 3 \\ 8 & 0 & 6 & 1 \end{array}\right), \left(\begin{array}{rrrr} 2 & 6 & 5 & 4 \\ 3 & 10 & 4 & 8 \\ 7 & 7 & 7 & 5 \\ 4 & 9 & 8 & 7 \end{array}\right)$ Copy content Toggle raw display
Nilpotency class: $2$
Derived length: $2$

The subgroup is nonabelian, a $p$-group (hence nilpotent, solvable, supersolvable, monomial, elementary, and hyperelementary), and metabelian.

Ambient group ($G$) information

Description: $C_{11}^3:(C_{11}:C_5)$
Order: \(73205\)\(\medspace = 5 \cdot 11^{4} \)
Exponent: \(55\)\(\medspace = 5 \cdot 11 \)
Derived length:$3$

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

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)$$\He_{11}:C_{10}^2$, of order \(133100\)\(\medspace = 2^{2} \cdot 5^{2} \cdot 11^{3} \)
$\operatorname{Aut}(H)$ $C_{11}^2.\GL(2,11)$, of order \(1597200\)\(\medspace = 2^{4} \cdot 3 \cdot 5^{2} \cdot 11^{3} \)
$\card{W}$\(1331\)\(\medspace = 11^{3} \)
