Subgroup ($H$) information

Description:$D_6$
Order: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Index: \(112\)\(\medspace = 2^{4} \cdot 7 \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $a, bd, e^{14}$ Copy content Toggle raw display
Derived length: $2$

The subgroup is nonabelian, metacyclic (hence solvable, supersolvable, monomial, and metabelian), hyperelementary for $p = 2$, an A-group, and rational.

Ambient group ($G$) information

Description: $C_{84}.C_2^4$
Order: \(1344\)\(\medspace = 2^{6} \cdot 3 \cdot 7 \)
Exponent: \(84\)\(\medspace = 2^{2} \cdot 3 \cdot 7 \)
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 $W = N_G(H) / Z_G(H)$.
