Subgroup ($H$) information

Description:$C_{10}$
Order: \(10\)\(\medspace = 2 \cdot 5 \)
Index: \(5280\)\(\medspace = 2^{5} \cdot 3 \cdot 5 \cdot 11 \)
Exponent: \(10\)\(\medspace = 2 \cdot 5 \)
Generators: $\left(\begin{array}{rrrr} 1 & 1 & 6 & 7 \\ 3 & 3 & 0 & 6 \\ 4 & 2 & 8 & 10 \\ 9 & 4 & 8 & 10 \end{array}\right), \left(\begin{array}{rrrr} 9 & 0 & 0 & 0 \\ 0 & 9 & 0 & 0 \\ 0 & 0 & 9 & 0 \\ 0 & 0 & 0 & 9 \end{array}\right)$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,5$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).

Ambient group ($G$) information

Description: $\GL(2,11):C_2^2$
Order: \(52800\)\(\medspace = 2^{6} \cdot 3 \cdot 5^{2} \cdot 11 \)
Exponent: \(1320\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \cdot 11 \)
Derived length:$1$

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_4\times \PSL(2,11).C_2\times D_4$
$\operatorname{Aut}(H)$ $C_4$, of order \(4\)\(\medspace = 2^{2} \)
$W$$C_1$, of order $1$
