Subgroup ($H$) information

Description:$C_{11}:Q_8$
Order: \(88\)\(\medspace = 2^{3} \cdot 11 \)
Index: \(20\)\(\medspace = 2^{2} \cdot 5 \)
Exponent: \(44\)\(\medspace = 2^{2} \cdot 11 \)
Generators: $ab^{25}c, b^{20}, c^{2}, b^{30}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_{11}:(C_{10}\times Q_{16})$
Order: \(1760\)\(\medspace = 2^{5} \cdot 5 \cdot 11 \)
Exponent: \(440\)\(\medspace = 2^{3} \cdot 5 \cdot 11 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_2\times C_{10}$
Order: \(20\)\(\medspace = 2^{2} \cdot 5 \)
Exponent: \(10\)\(\medspace = 2 \cdot 5 \)
Automorphism Group: $C_4\times S_3$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
Outer Automorphisms: $C_4\times S_3$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
Derived length: $1$

The quotient is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), elementary for $p = 2$ (hence hyperelementary), and metacyclic.

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}.(C_{10}\times D_4).C_2^4$
$\operatorname{Aut}(H)$ $D_4\times F_{11}$, of order \(880\)\(\medspace = 2^{4} \cdot 5 \cdot 11 \)
$\operatorname{res}(S)$$D_4\times F_{11}$, of order \(880\)\(\medspace = 2^{4} \cdot 5 \cdot 11 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(8\)\(\medspace = 2^{3} \)
$W$$D_{22}:C_{10}$, of order \(440\)\(\medspace = 2^{3} \cdot 5 \cdot 11 \)
