Subgroup ($H$) information

Description:$C_3^2:C_6$
Order: \(54\)\(\medspace = 2 \cdot 3^{3} \)
Index: \(144\)\(\medspace = 2^{4} \cdot 3^{2} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $\langle(10,17,13)(12,14,16), (11,15,18)(12,14,16), (2,3)(6,7)(11,12,15,14,18,16)(13,17), (5,7,6)(11,18,15)(12,16,14)\rangle$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_6^3:S_3^2$
Order: \(7776\)\(\medspace = 2^{5} \cdot 3^{5} \)
Exponent: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
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_2\times C_6^2.C_3^4.C_2^4$
$\operatorname{Aut}(H)$ $C_2\times C_3^2:\GL(2,3)$, of order \(864\)\(\medspace = 2^{5} \cdot 3^{3} \)
$W$$S_3^2$, of order \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
