Subgroup ($H$) information

Description:$C_2^2:C_6^2$
Order: \(144\)\(\medspace = 2^{4} \cdot 3^{2} \)
Index: \(28\)\(\medspace = 2^{2} \cdot 7 \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $ab^{3}, e, de, c^{42}, b^{2}, c^{28}e$ Copy content Toggle raw display
Derived length: $2$

The subgroup is nonabelian, monomial (hence solvable), 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 $W = N_G(H) / Z_G(H)$.
