Subgroup ($H$) information

Description:$C_2\times \SD_{16}$
Order: \(32\)\(\medspace = 2^{5} \)
Index: \(8\)\(\medspace = 2^{3} \)
Exponent: \(8\)\(\medspace = 2^{3} \)
Generators: $acd, bc^{2}de^{6}, e$ Copy content Toggle raw display
Nilpotency class: $3$
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_4.D_4^2$
Order: \(256\)\(\medspace = 2^{8} \)
Exponent: \(8\)\(\medspace = 2^{3} \)
Nilpotency class:$3$
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_2^6.C_2^6.C_2$
$\operatorname{Aut}(H)$ $D_4^2:C_2$, of order \(128\)\(\medspace = 2^{7} \)
$\card{W}$\(16\)\(\medspace = 2^{4} \)
