Subgroup ($H$) information
Description: | $C_7$ |
Order: | \(7\) |
Index: | \(256\)\(\medspace = 2^{8} \) |
Exponent: | \(7\) |
Generators: |
$a^{2}$
|
Nilpotency class: | $1$ |
Derived length: | $1$ |
The subgroup is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), a $7$-Sylow subgroup (hence a Hall subgroup), a $p$-group, and simple.
Ambient group ($G$) information
Description: | $C_2^5:F_8$ |
Order: | \(1792\)\(\medspace = 2^{8} \cdot 7 \) |
Exponent: | \(28\)\(\medspace = 2^{2} \cdot 7 \) |
Derived length: | $2$ |
The ambient group is nonabelian, monomial (hence solvable), 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 $W = N_G(H) / Z_G(H)$.
$\operatorname{Aut}(G)$ | $C_2^6:C_7.A_4.C_2^2$ |
$\operatorname{Aut}(H)$ | $C_6$, of order \(6\)\(\medspace = 2 \cdot 3 \) |
$\operatorname{res}(S)$ | $C_3$, of order \(3\) |
$\card{\operatorname{ker}(\operatorname{res})}$ | \(112\)\(\medspace = 2^{4} \cdot 7 \) |
$W$ | $C_1$, of order $1$ |
