Subgroup ($H$) information
Description: | $C_{26}:C_4$ |
Order: | \(104\)\(\medspace = 2^{3} \cdot 13 \) |
Index: | \(4\)\(\medspace = 2^{2} \) |
Exponent: | \(52\)\(\medspace = 2^{2} \cdot 13 \) |
Generators: |
$ac, a^{2}bc^{6}, c^{4}, bc^{26}$
|
Derived length: | $2$ |
The subgroup is nonabelian, metacyclic (hence solvable, supersolvable, monomial, and metabelian), hyperelementary for $p = 2$, and an A-group.
Ambient group ($G$) information
Description: | $C_{26}.C_4^2$ |
Order: | \(416\)\(\medspace = 2^{5} \cdot 13 \) |
Exponent: | \(52\)\(\medspace = 2^{2} \cdot 13 \) |
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 $W = N_G(H) / Z_G(H)$.
$\operatorname{Aut}(G)$ | $C_2^2\wr C_2\times F_{13}$, of order \(4992\)\(\medspace = 2^{7} \cdot 3 \cdot 13 \) |
$\operatorname{Aut}(H)$ | $C_2\times F_{13}$, of order \(312\)\(\medspace = 2^{3} \cdot 3 \cdot 13 \) |
$\operatorname{res}(S)$ | $C_2\times F_{13}$, of order \(312\)\(\medspace = 2^{3} \cdot 3 \cdot 13 \) |
$\card{\operatorname{ker}(\operatorname{res})}$ | \(4\)\(\medspace = 2^{2} \) |
$W$ | $C_{13}:C_4$, of order \(52\)\(\medspace = 2^{2} \cdot 13 \) |
