Subgroup ($H$) information

Description:$C_6\times Q_8$
Order: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Index: \(34\)\(\medspace = 2 \cdot 17 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $a, d^{102}, c, d^{51}, d^{136}$ Copy content Toggle raw display
Nilpotency class: $2$
Derived length: $2$

The subgroup is nonabelian, elementary for $p = 2$ (hence nilpotent, solvable, supersolvable, monomial, and hyperelementary), and metabelian.

Ambient group ($G$) information

Description: $C_{204}.C_2^3$
Order: \(1632\)\(\medspace = 2^{5} \cdot 3 \cdot 17 \)
Exponent: \(204\)\(\medspace = 2^{2} \cdot 3 \cdot 17 \)
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_2^4.C_2^4.C_{51}.C_8.C_2^4$
$\operatorname{Aut}(H)$ $C_2^4:S_4$, of order \(384\)\(\medspace = 2^{7} \cdot 3 \)
$\operatorname{res}(S)$$C_2^4:D_4$, of order \(128\)\(\medspace = 2^{7} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(64\)\(\medspace = 2^{6} \)
$W$$C_2^2$, of order \(4\)\(\medspace = 2^{2} \)
