Subgroup ($H$) information

Description:$C_2\times C_6$
Order: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Index: \(132\)\(\medspace = 2^{2} \cdot 3 \cdot 11 \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $a, c^{66}, b^{2}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

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

Ambient group ($G$) information

Description: $D_{66}:C_{12}$
Order: \(1584\)\(\medspace = 2^{4} \cdot 3^{2} \cdot 11 \)
Exponent: \(132\)\(\medspace = 2^{2} \cdot 3 \cdot 11 \)
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 $W = N_G(H) / Z_G(H)$.
