Subgroup ($H$) information

Description:$Q_{32}$
Order: \(32\)\(\medspace = 2^{5} \)
Index: \(8\)\(\medspace = 2^{3} \)
Exponent: \(16\)\(\medspace = 2^{4} \)
Generators: $ac^{4}, b$ Copy content Toggle raw display
Nilpotency class: $4$
Derived length: $2$

The subgroup is nonabelian, a $p$-group (hence nilpotent, solvable, supersolvable, monomial, elementary, and hyperelementary), and metacyclic (hence metabelian).

Ambient group ($G$) information

Description: $C_{16}.D_8$
Order: \(256\)\(\medspace = 2^{8} \)
Exponent: \(16\)\(\medspace = 2^{4} \)
Nilpotency class:$4$
Derived length:$2$

The ambient group is nonabelian, a $p$-group (hence nilpotent, solvable, supersolvable, monomial, elementary, and hyperelementary), 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.C_4^3.C_2^5$
$\operatorname{Aut}(H)$ $D_{16}:C_4$, of order \(128\)\(\medspace = 2^{7} \)
$\operatorname{res}(S)$$D_8:C_4$, of order \(64\)\(\medspace = 2^{6} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(8\)\(\medspace = 2^{3} \)
$W$$C_2\times D_8$, of order \(32\)\(\medspace = 2^{5} \)
