Subgroup ($H$) information

Description:$C_8.D_4$
Order: \(64\)\(\medspace = 2^{6} \)
Index: \(4\)\(\medspace = 2^{2} \)
Exponent: \(8\)\(\medspace = 2^{3} \)
Generators: $ac, b, de$ 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), metabelian, and rational.

Ambient group ($G$) information

Description: $C_4^2.C_2^4$
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_2^9.C_2^4$
$\operatorname{Aut}(H)$ $C_2^6.C_2^4$, of order \(1024\)\(\medspace = 2^{10} \)
$\card{W}$\(32\)\(\medspace = 2^{5} \)
