Subgroup ($H$) information

Description:$C_3^2:C_{12}$
Order: \(108\)\(\medspace = 2^{2} \cdot 3^{3} \)
Index: \(16\)\(\medspace = 2^{4} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $bd^{11}e^{3}, d^{4}, e^{2}, d^{6}, c^{2}$ Copy content Toggle raw display
Derived length: $2$

The subgroup is normal, nonabelian, supersolvable (hence solvable and monomial), metabelian, and an A-group.

Ambient group ($G$) information

Description: $C_{12}.D_6^2$
Order: \(1728\)\(\medspace = 2^{6} \cdot 3^{3} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Derived length:$2$

The ambient group is nonabelian, supersolvable (hence solvable and monomial), and metabelian.

Quotient group ($Q$) structure

Description: $C_2^4$
Order: \(16\)\(\medspace = 2^{4} \)
Exponent: \(2\)
Automorphism Group: $A_8$, of order \(20160\)\(\medspace = 2^{6} \cdot 3^{2} \cdot 5 \cdot 7 \)
Outer Automorphisms: $A_8$, of order \(20160\)\(\medspace = 2^{6} \cdot 3^{2} \cdot 5 \cdot 7 \)
Derived length: $1$

The quotient is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), a $p$-group (hence elementary and hyperelementary), 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 $W = N_G(H) / Z_G(H)$.

$\operatorname{Aut}(G)$$C_6^3.C_2^6.C_2^5$
$\operatorname{Aut}(H)$ $C_6^2:\GL(2,3)$, of order \(1728\)\(\medspace = 2^{6} \cdot 3^{3} \)
$\card{W}$\(72\)\(\medspace = 2^{3} \cdot 3^{2} \)
