Subgroup ($H$) information

Description:$C_3\times S_3$
Order: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Index: \(27\)\(\medspace = 3^{3} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $a^{3}, a^{2}, bd^{6}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $(C_3^2\times C_9):C_6$
Order: \(486\)\(\medspace = 2 \cdot 3^{5} \)
Exponent: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Derived length:$2$

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

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.S_3^3$, of order \(52488\)\(\medspace = 2^{3} \cdot 3^{8} \)
$\operatorname{Aut}(H)$ $D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
$\operatorname{res}(S)$$D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
