Subgroup ($H$) information

Description:$C_3^2$
Order: \(9\)\(\medspace = 3^{2} \)
Index: \(192\)\(\medspace = 2^{6} \cdot 3 \)
Exponent: \(3\)
Generators: $b^{4}, d$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

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

Ambient group ($G$) information

Description: $C_6^3.C_2^3$
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: $C_{12}:C_4^2$
Order: \(192\)\(\medspace = 2^{6} \cdot 3 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Automorphism Group: $(C_2^9\times S_3).C_2$, of order \(6144\)\(\medspace = 2^{11} \cdot 3 \)
Outer Automorphisms: $C_2^5:D_4$, of order \(256\)\(\medspace = 2^{8} \)
Nilpotency class: $-1$
Derived length: $2$

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

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

$\operatorname{Aut}(G)$Group of order \(1327104\)\(\medspace = 2^{14} \cdot 3^{4} \)
$\operatorname{Aut}(H)$ $\GL(2,3)$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \)
$\card{W}$\(4\)\(\medspace = 2^{2} \)
