Subgroup ($H$) information

Description:$C_3:C_8$
Order: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Index: \(81\)\(\medspace = 3^{4} \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Generators: $a, a^{2}, a^{4}, d$ Copy content Toggle raw display
Derived length: $2$

The subgroup is nonabelian, a Z-group (hence solvable, supersolvable, monomial, metacyclic, metabelian, and an A-group), and hyperelementary for $p = 2$.

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 \(5598720\)\(\medspace = 2^{9} \cdot 3^{7} \cdot 5 \)
$\operatorname{Aut}(H)$ $C_2\times D_6$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
$\operatorname{res}(S)$$D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(5760\)\(\medspace = 2^{7} \cdot 3^{2} \cdot 5 \)
$W$$S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \)
