Subgroup ($H$) information

Description:$C_3:F_9$
Order: \(216\)\(\medspace = 2^{3} \cdot 3^{3} \)
Index: \(9\)\(\medspace = 3^{2} \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Generators: $a, d, cef^{2}, a^{2}, a^{4}, bf$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_3^3:F_9$
Order: \(1944\)\(\medspace = 2^{3} \cdot 3^{5} \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Derived length:$2$

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

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_3^5.C_4.C_2^2.A_6.C_2^2$, of order \(5598720\)\(\medspace = 2^{9} \cdot 3^{7} \cdot 5 \)
$\operatorname{Aut}(H)$ $F_9:D_6$, of order \(864\)\(\medspace = 2^{5} \cdot 3^{3} \)
$\operatorname{res}(S)$$F_9:D_6$, of order \(864\)\(\medspace = 2^{5} \cdot 3^{3} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(72\)\(\medspace = 2^{3} \cdot 3^{2} \)
$W$$C_3:F_9$, of order \(216\)\(\medspace = 2^{3} \cdot 3^{3} \)
