Subgroup ($H$) information
| Description: | $C_2$ |
| Order: | \(2\) |
| Index: | \(272\)\(\medspace = 2^{4} \cdot 17 \) |
| Exponent: | \(2\) |
| Generators: |
$a^{2}b$
|
| Nilpotency class: | $1$ |
| Derived length: | $1$ |
The subgroup is normal, cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), central, a $p$-group, simple, and rational.
Ambient group ($G$) information
| Description: | $C_{34}.C_4^2$ |
| Order: | \(544\)\(\medspace = 2^{5} \cdot 17 \) |
| Exponent: | \(68\)\(\medspace = 2^{2} \cdot 17 \) |
| Derived length: | $2$ |
The ambient group is nonabelian, supersolvable (hence solvable and monomial), hyperelementary for $p = 2$, and metabelian.
Quotient group ($Q$) structure
| Description: | $C_{34}.D_4$ |
| Order: | \(272\)\(\medspace = 2^{4} \cdot 17 \) |
| Exponent: | \(68\)\(\medspace = 2^{2} \cdot 17 \) |
| Automorphism Group: | $C_{17}:(C_2^4\times C_{16})$, of order \(4352\)\(\medspace = 2^{8} \cdot 17 \) |
| Outer Automorphisms: | $C_2^2\times C_{16}$, of order \(64\)\(\medspace = 2^{6} \) |
| Nilpotency class: | $-1$ |
| Derived length: | $2$ |
The quotient is nonabelian, supersolvable (hence solvable and monomial), hyperelementary for $p = 2$, and metabelian.
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 $W = N_G(H) / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $C_{17}:((C_2^6\times C_{16}).C_2)$ |
| $\operatorname{Aut}(H)$ | $C_1$, of order $1$ |
| $\operatorname{res}(S)$ | $C_1$, of order $1$ |
| $\card{\operatorname{ker}(\operatorname{res})}$ | \(17408\)\(\medspace = 2^{10} \cdot 17 \) |
| $W$ | $C_1$, of order $1$ |
