Subgroup ($H$) information

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

The subgroup is characteristic (hence 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: $(C_2\times C_4).S_3^3$
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: $C_2.(Q_8\times D_6)$
Order: \(192\)\(\medspace = 2^{6} \cdot 3 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Automorphism Group: $C_2^2.(D_6\times C_2^6)$, of order \(3072\)\(\medspace = 2^{10} \cdot 3 \)
Outer Automorphisms: $C_2^6$, of order \(64\)\(\medspace = 2^{6} \)
Nilpotency class: $-1$
Derived length: $2$

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

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 $W = G / Z_G(H)$.

$\operatorname{Aut}(G)$Group of order \(55296\)\(\medspace = 2^{11} \cdot 3^{3} \)
$\operatorname{Aut}(H)$ $\GL(2,3)$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \)
$\card{W}$\(4\)\(\medspace = 2^{2} \)
