Subgroup ($H$) information

Description:$C_{11}:Q_8$
Order: \(88\)\(\medspace = 2^{3} \cdot 11 \)
Index: \(220\)\(\medspace = 2^{2} \cdot 5 \cdot 11 \)
Exponent: \(44\)\(\medspace = 2^{2} \cdot 11 \)
Generators: $a^{5}bd^{19}, d^{22}, cd^{28}, b^{2}c$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_{11}^2:(C_{10}\times \SD_{16})$
Order: \(19360\)\(\medspace = 2^{5} \cdot 5 \cdot 11^{2} \)
Exponent: \(440\)\(\medspace = 2^{3} \cdot 5 \cdot 11 \)
Derived length:$3$

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

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_{11}^2.C_2^3.C_5.C_2^5$
$\operatorname{Aut}(H)$ $D_4\times F_{11}$, of order \(880\)\(\medspace = 2^{4} \cdot 5 \cdot 11 \)
$W$$C_2^2\times F_{11}$, of order \(440\)\(\medspace = 2^{3} \cdot 5 \cdot 11 \)
