Subgroup ($H$) information

Description:$D_4$
Order: \(8\)\(\medspace = 2^{3} \)
Index: \(216\)\(\medspace = 2^{3} \cdot 3^{3} \)
Exponent: \(4\)\(\medspace = 2^{2} \)
Generators: $ac^{2}, bc^{5}$ 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), metacyclic (hence metabelian), and rational.

Ambient group ($G$) information

Description: $C_{12}.D_6^2$
Order: \(1728\)\(\medspace = 2^{6} \cdot 3^{3} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Derived length:$2$

The ambient group is nonabelian, supersolvable (hence solvable and monomial), 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_6^3.C_2^6.C_2^5$
$\operatorname{Aut}(H)$ $D_4$, of order \(8\)\(\medspace = 2^{3} \)
$\card{W}$\(4\)\(\medspace = 2^{2} \)
