Subgroup ($H$) information

Description:$C_2\times \PSU(3,2)$
Order: \(144\)\(\medspace = 2^{4} \cdot 3^{2} \)
Index: \(216\)\(\medspace = 2^{3} \cdot 3^{3} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $\langle(7,12)(8,11)(9,10)(13,15), (1,3)(5,6)(7,12,14)(8,10,15)(9,11,13), (1,5) \!\cdots\! \rangle$ Copy content Toggle raw display
Derived length: $3$

The subgroup is nonabelian, monomial (hence solvable), and rational.

Ambient group ($G$) information

Description: $C_3^4:(D_4\times \GL(2,3))$
Order: \(31104\)\(\medspace = 2^{7} \cdot 3^{5} \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Derived length:$5$

The ambient group is nonabelian and solvable. Whether it is monomial has not been computed.

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.C_6^2.C_6.D_4.C_2$, of order \(62208\)\(\medspace = 2^{8} \cdot 3^{5} \)
$\operatorname{Aut}(H)$ $C_6^2:\GL(2,3)$, of order \(1728\)\(\medspace = 2^{6} \cdot 3^{3} \)
$W$$F_9:C_2^2$, of order \(288\)\(\medspace = 2^{5} \cdot 3^{2} \)
