Subgroup ($H$) information

Description:$C_3^3:Q_8$
Order: \(216\)\(\medspace = 2^{3} \cdot 3^{3} \)
Index: \(240\)\(\medspace = 2^{4} \cdot 3 \cdot 5 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $\langle(7,12)(8,11)(9,10)(13,15), (1,5,4)(2,6,3)(7,15,13,8)(9,11,14,12), (7,14,12) \!\cdots\! \rangle$ Copy content Toggle raw display
Derived length: $3$

The subgroup is nonabelian and monomial (hence solvable).

Ambient group ($G$) information

Description: $F_9:S_6$
Order: \(51840\)\(\medspace = 2^{7} \cdot 3^{4} \cdot 5 \)
Exponent: \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \)
Derived length:$3$

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)$$\PSU(3,2):C_2.A_6.C_2^2$, of order \(207360\)\(\medspace = 2^{9} \cdot 3^{4} \cdot 5 \)
$\operatorname{Aut}(H)$ $C_2\times C_3^2:\GL(2,3)$, of order \(864\)\(\medspace = 2^{5} \cdot 3^{3} \)
$W$$F_9:C_2^2$, of order \(288\)\(\medspace = 2^{5} \cdot 3^{2} \)
