Subgroup ($H$) information
| Description: | $C_{44}.D_8$ |
| Order: | \(704\)\(\medspace = 2^{6} \cdot 11 \) |
| Index: | $1$ |
| Exponent: | \(88\)\(\medspace = 2^{3} \cdot 11 \) |
| Generators: |
$a, c^{22}, b^{2}c^{11}, c^{33}, b, c^{4}, b^{4}c^{22}$
|
| Derived length: | $2$ |
The subgroup is the radical (hence characteristic, normal, and solvable), a direct factor, nonabelian, a Hall subgroup, supersolvable (hence monomial), hyperelementary for $p = 2$, and metabelian.
Ambient group ($G$) information
| Description: | $C_{44}.D_8$ |
| Order: | \(704\)\(\medspace = 2^{6} \cdot 11 \) |
| Exponent: | \(88\)\(\medspace = 2^{3} \cdot 11 \) |
| Derived length: | $2$ |
The ambient group is nonabelian, supersolvable (hence solvable and monomial), hyperelementary for $p = 2$, and metabelian.
Quotient group ($Q$) structure
| Description: | $C_1$ |
| Order: | $1$ |
| Exponent: | $1$ |
| Automorphism Group: | $C_1$, of order $1$ |
| Outer Automorphisms: | $C_1$, of order $1$ |
| Derived length: | $0$ |
The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary (for every $p$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), a $p$-group (for every $p$), perfect, and rational.
Automorphism information
Since the subgroup $H$ is characteristic, the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : \operatorname{Aut}(G) \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphism group $\operatorname{Inn}(G)$ is the Weyl group $W = G / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $C_{22}.(C_2^5\times C_{10}).C_2^2$ |
| $\operatorname{Aut}(H)$ | $C_{22}.(C_2^5\times C_{10}).C_2^2$ |
| $W$ | $C_{22}.D_4$, of order \(176\)\(\medspace = 2^{4} \cdot 11 \) |
