Subgroup ($H$) information

Description:$C_3^3:C_8$
Order: \(216\)\(\medspace = 2^{3} \cdot 3^{3} \)
Index: \(81\)\(\medspace = 3^{4} \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Generators: $a, g, eh^{2}, a^{2}, a^{4}, degh^{2}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $(C_3^2\times \He_3).F_9$
Order: \(17496\)\(\medspace = 2^{3} \cdot 3^{7} \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Derived length:$3$

The ambient group is nonabelian and monomial (hence solvable).

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_3^3.C_3^4.C_2.D_4^2$, of order \(279936\)\(\medspace = 2^{7} \cdot 3^{7} \)
$\operatorname{Aut}(H)$ $C_2\times F_9:D_6$, of order \(1728\)\(\medspace = 2^{6} \cdot 3^{3} \)
$W$$C_3^3:C_4$, of order \(108\)\(\medspace = 2^{2} \cdot 3^{3} \)
