Subgroup ($H$) information

Description:$C_3\times C_6$
Order: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Index: \(96\)\(\medspace = 2^{5} \cdot 3 \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $d^{6}, d^{4}, e^{2}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is normal, abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), elementary for $p = 3$ (hence hyperelementary), and metacyclic.

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: $C_2^3\times D_6$
Order: \(96\)\(\medspace = 2^{5} \cdot 3 \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Automorphism Group: $C_2^4.A_8\times S_3$, of order \(1935360\)\(\medspace = 2^{11} \cdot 3^{3} \cdot 5 \cdot 7 \)
Outer Automorphisms: $C_2^4.A_8$, of order \(322560\)\(\medspace = 2^{10} \cdot 3^{2} \cdot 5 \cdot 7 \)
Nilpotency class: $-1$
Derived length: $2$

The quotient is nonabelian, supersolvable (hence solvable and monomial), hyperelementary for $p = 2$, metabelian, an A-group, 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$
$\operatorname{Aut}(H)$ $\GL(2,3)$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \)
$\card{W}$\(4\)\(\medspace = 2^{2} \)
