Subgroup ($H$) information

Description:$S_3\times D_7$
Order: \(84\)\(\medspace = 2^{2} \cdot 3 \cdot 7 \)
Index: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Exponent: \(42\)\(\medspace = 2 \cdot 3 \cdot 7 \)
Generators: $ac^{49}e, c^{28}, c^{12}, b^{3}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_{28}:(C_6\times S_4)$
Order: \(4032\)\(\medspace = 2^{6} \cdot 3^{2} \cdot 7 \)
Exponent: \(84\)\(\medspace = 2^{2} \cdot 3 \cdot 7 \)
Derived length:$3$

The ambient group is nonabelian and monomial (hence solvable).

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 $W = N_G(H) / Z_G(H)$.
