Subgroup ($H$) information

Description:$C_{22}:C_4$
Order: \(88\)\(\medspace = 2^{3} \cdot 11 \)
Index: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Exponent: \(44\)\(\medspace = 2^{2} \cdot 11 \)
Generators: $a, a^{2}, b^{24}, b^{132}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_{264}:C_4$
Order: \(1056\)\(\medspace = 2^{5} \cdot 3 \cdot 11 \)
Exponent: \(264\)\(\medspace = 2^{3} \cdot 3 \cdot 11 \)
Derived length:$2$

The ambient group is nonabelian, metacyclic (hence solvable, supersolvable, monomial, and metabelian), and hyperelementary for $p = 2$.

Quotient group ($Q$) structure

Description: $C_{12}$
Order: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Automorphism Group: $C_2^2$, of order \(4\)\(\medspace = 2^{2} \)
Outer Automorphisms: $C_2^2$, of order \(4\)\(\medspace = 2^{2} \)
Derived length: $1$

The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,3$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).

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