Subgroup ($H$) information

Description:$C_2\times D_4$
Order: \(16\)\(\medspace = 2^{4} \)
Index: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Exponent: \(4\)\(\medspace = 2^{2} \)
Generators: $ce^{3}, a^{2}b, be^{3}$ Copy content Toggle raw display
Nilpotency class: $2$
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: $(C_2^3\times C_{12}).D_4$
Order: \(768\)\(\medspace = 2^{8} \cdot 3 \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
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_3:(C_2^8.C_2^5)$
$\operatorname{Aut}(H)$ $C_2\wr C_2^2$, of order \(64\)\(\medspace = 2^{6} \)
$\card{W}$\(4\)\(\medspace = 2^{2} \)
