Subgroup ($H$) information

Description:$S_3\times D_{22}$
Order: \(264\)\(\medspace = 2^{3} \cdot 3 \cdot 11 \)
Index: \(4\)\(\medspace = 2^{2} \)
Exponent: \(66\)\(\medspace = 2 \cdot 3 \cdot 11 \)
Generators: $ac, d^{22}, b^{2}d^{22}, b^{3}cd^{23}, d^{4}$ Copy content Toggle raw display
Derived length: $2$

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

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: $C_2^2$
Order: \(4\)\(\medspace = 2^{2} \)
Exponent: \(2\)
Automorphism Group: $S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \)
Outer Automorphisms: $S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \)
Derived length: $1$

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

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