Subgroup ($H$) information
| Description: | $C_{88}.C_{10}$ |
| Order: | \(880\)\(\medspace = 2^{4} \cdot 5 \cdot 11 \) |
| Index: | \(2\) |
| Exponent: | \(440\)\(\medspace = 2^{3} \cdot 5 \cdot 11 \) |
| Generators: |
$a^{5}, b^{16}, a^{2}b^{88}, b^{132}, b^{110}, b^{88}$
|
| Derived length: | $2$ |
The subgroup is normal, maximal, nonabelian, and metacyclic (hence solvable, supersolvable, monomial, and metabelian).
Ambient group ($G$) information
| Description: | $C_{176}.C_{10}$ |
| Order: | \(1760\)\(\medspace = 2^{5} \cdot 5 \cdot 11 \) |
| Exponent: | \(880\)\(\medspace = 2^{4} \cdot 5 \cdot 11 \) |
| Derived length: | $2$ |
The ambient group is nonabelian and metacyclic (hence solvable, supersolvable, monomial, and metabelian).
Quotient group ($Q$) structure
| Description: | $C_2$ |
| Order: | \(2\) |
| Exponent: | \(2\) |
| Automorphism Group: | $C_1$, of order $1$ |
| Outer Automorphisms: | $C_1$, of order $1$ |
| Derived length: | $1$ |
The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), a $p$-group, simple, and rational.
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 $W = N_G(H) / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $C_{88}.C_{10}.C_2^4$ |
| $\operatorname{Aut}(H)$ | $D_8:C_2\times F_{11}$, of order \(3520\)\(\medspace = 2^{6} \cdot 5 \cdot 11 \) |
| $\operatorname{res}(S)$ | $D_8:C_2\times F_{11}$, of order \(3520\)\(\medspace = 2^{6} \cdot 5 \cdot 11 \) |
| $\card{\operatorname{ker}(\operatorname{res})}$ | \(2\) |
| $W$ | $C_{88}:C_{10}$, of order \(880\)\(\medspace = 2^{4} \cdot 5 \cdot 11 \) |
