Subgroup ($H$) information
Description: | $C_{11}:Q_{16}$ |
Order: | \(176\)\(\medspace = 2^{4} \cdot 11 \) |
Index: | \(7\) |
Exponent: | \(88\)\(\medspace = 2^{3} \cdot 11 \) |
Generators: |
$a, b^{6}, b^{4}, b, c^{7}$
|
Derived length: | $2$ |
The subgroup is maximal, nonabelian, a Hall subgroup, supersolvable (hence solvable and monomial), hyperelementary for $p = 2$, and metabelian.
Ambient group ($G$) information
Description: | $C_{77}:Q_{16}$ |
Order: | \(1232\)\(\medspace = 2^{4} \cdot 7 \cdot 11 \) |
Exponent: | \(616\)\(\medspace = 2^{3} \cdot 7 \cdot 11 \) |
Derived length: | $2$ |
The ambient group 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 $W = N_G(H) / Z_G(H)$.
$\operatorname{Aut}(G)$ | $C_{77}.C_{30}.C_2^5$ |
$\operatorname{Aut}(H)$ | $C_2\times D_4\times F_{11}$, of order \(1760\)\(\medspace = 2^{5} \cdot 5 \cdot 11 \) |
$\operatorname{res}(S)$ | $C_2\times D_4\times F_{11}$, of order \(1760\)\(\medspace = 2^{5} \cdot 5 \cdot 11 \) |
$\card{\operatorname{ker}(\operatorname{res})}$ | \(6\)\(\medspace = 2 \cdot 3 \) |
$W$ | $C_{11}:D_4$, of order \(88\)\(\medspace = 2^{3} \cdot 11 \) |
