Subgroup ($H$) information

Description:$D_{132}:C_2$
Order: \(528\)\(\medspace = 2^{4} \cdot 3 \cdot 11 \)
Index: \(2\)
Exponent: \(132\)\(\medspace = 2^{2} \cdot 3 \cdot 11 \)
Generators: $ac, d^{4}, d^{11}, d^{22}, b^{3}, b^{2}d^{22}$ Copy content Toggle raw display
Derived length: $2$

The subgroup is characteristic (hence normal), maximal, a semidirect factor, nonabelian, supersolvable (hence solvable and monomial), hyperelementary for $p = 2$, and metabelian.

Ambient group ($G$) information

Description: $D_{12}:D_{22}$
Order: \(1056\)\(\medspace = 2^{5} \cdot 3 \cdot 11 \)
Exponent: \(132\)\(\medspace = 2^{2} \cdot 3 \cdot 11 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_2$
Order: \(2\)
Exponent: \(2\)
Automorphism Group: $C_1$, of order $1$
Outer Automorphisms: $C_1$, of order $1$
Derived length: $1$

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

Automorphism information

Since the subgroup $H$ is characteristic, the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : \operatorname{Aut}(G) \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphism group $\operatorname{Inn}(G)$ is the Weyl group $W = G / Z_G(H)$.
