Subgroup ($H$) information

Description:$C_3:F_9$
Order: \(216\)\(\medspace = 2^{3} \cdot 3^{3} \)
Index: \(2\)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Generators: $ab, d, c, b^{18}, b^{12}, b^{8}$ Copy content Toggle raw display
Derived length: $2$

The subgroup is characteristic (hence normal), maximal, a semidirect factor, nonabelian, monomial (hence solvable), metabelian, and an A-group.

Ambient group ($G$) information

Description: $S_3\times F_9$
Order: \(432\)\(\medspace = 2^{4} \cdot 3^{3} \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_2$
Order: \(2\)
Exponent: \(2\)
Automorphism Group: $C_1$, of order $1$
Outer Automorphisms: $C_1$, of order $1$
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)$$F_9:D_6$, of order \(864\)\(\medspace = 2^{5} \cdot 3^{3} \)
$\operatorname{Aut}(H)$ $F_9:D_6$, of order \(864\)\(\medspace = 2^{5} \cdot 3^{3} \)
$\operatorname{res}(\operatorname{Aut}(G))$$F_9:D_6$, of order \(864\)\(\medspace = 2^{5} \cdot 3^{3} \)
$\card{\operatorname{ker}(\operatorname{res})}$$1$
$W$$S_3\times F_9$, of order \(432\)\(\medspace = 2^{4} \cdot 3^{3} \)
