Subgroup ($H$) information

Description:$C_3^2:C_6$
Order: \(54\)\(\medspace = 2 \cdot 3^{3} \)
Index: \(360\)\(\medspace = 2^{3} \cdot 3^{2} \cdot 5 \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $\langle(7,8,9)(10,12,11), (1,3,6)(2,5,4)(7,8,9)(10,11,12)(13,14,15), (2,4)(3,6)(7,10,9,11,8,12)(13,14), (7,9,8)(10,12,11)(13,15,14)\rangle$ 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: $C_3^2:C_6\times A_6$
Order: \(19440\)\(\medspace = 2^{4} \cdot 3^{5} \cdot 5 \)
Exponent: \(60\)\(\medspace = 2^{2} \cdot 3 \cdot 5 \)
Derived length:$2$

The ambient group is nonabelian and nonsolvable.

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.S_3^2.A_6.C_2^2$
$\operatorname{Aut}(H)$ $C_2\times C_3^2:\GL(2,3)$, of order \(864\)\(\medspace = 2^{5} \cdot 3^{3} \)
$W$$S_3^2$, of order \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
