Subgroup ($H$) information

Description:$C_3^2:C_6^2$
Order: \(324\)\(\medspace = 2^{2} \cdot 3^{4} \)
Index: \(2\)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $c^{3}, d^{2}, c^{2}, d^{3}, a^{2}, b$ Copy content Toggle raw display
Nilpotency class: $2$
Derived length: $2$

The subgroup is the Fitting subgroup (hence characteristic, normal, nilpotent, solvable, supersolvable, and monomial), maximal, a semidirect factor, nonabelian, and metabelian.

Ambient group ($G$) information

Description: $C_3\times C_6^2:C_6$
Order: \(648\)\(\medspace = 2^{3} \cdot 3^{4} \)
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: $C_2$
Order: \(2\)
Exponent: \(2\)
Automorphism Group: $C_1$, of order $1$
Outer Automorphisms: $C_1$, of order $1$
Nilpotency class: $1$
Derived length: $1$

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

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)$$C_2\times C_3^2.D_6^2$
$\operatorname{Aut}(H)$ $S_3\times C_3^4.Q_8.S_3^2$
$\operatorname{res}(\operatorname{Aut}(G))$$C_2\times S_3^3$, of order \(432\)\(\medspace = 2^{4} \cdot 3^{3} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(6\)\(\medspace = 2 \cdot 3 \)
$W$$C_3\times S_3$, of order \(18\)\(\medspace = 2 \cdot 3^{2} \)
