Subgroup ($H$) information

Description:$C_2\times C_4$
Order: \(8\)\(\medspace = 2^{3} \)
Index: \(507\)\(\medspace = 3 \cdot 13^{2} \)
Exponent: \(4\)\(\medspace = 2^{2} \)
Generators: $a, b^{3}c^{12}d^{7}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), a $2$-Sylow subgroup (hence a Hall subgroup), a $p$-group (hence elementary and hyperelementary), and metacyclic.

Ambient group ($G$) information

Description: $C_{13}^2:(C_4\times S_3)$
Order: \(4056\)\(\medspace = 2^{3} \cdot 3 \cdot 13^{2} \)
Exponent: \(156\)\(\medspace = 2^{2} \cdot 3 \cdot 13 \)
Derived length:$3$

The ambient group is nonabelian, monomial (hence solvable), and an A-group.

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)$$D_{13}^2.(C_6\times S_3)$, of order \(24336\)\(\medspace = 2^{4} \cdot 3^{2} \cdot 13^{2} \)
$\operatorname{Aut}(H)$ $D_4$, of order \(8\)\(\medspace = 2^{3} \)
$\operatorname{res}(S)$$C_2$, of order \(2\)
$\card{\operatorname{ker}(\operatorname{res})}$\(24\)\(\medspace = 2^{3} \cdot 3 \)
$W$$C_1$, of order $1$
