Subgroup ($H$) information

Description:$C_2\times C_3^2:C_4$
Order: \(72\)\(\medspace = 2^{3} \cdot 3^{2} \)
Index: \(560\)\(\medspace = 2^{4} \cdot 5 \cdot 7 \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $\langle(1,22)(2,42)(3,23)(4,32)(5,37)(6,40)(7,30)(8,25)(9,38)(10,39)(11,31)(12,26) \!\cdots\! \rangle$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $\PSL(3,4):C_2$
Order: \(40320\)\(\medspace = 2^{7} \cdot 3^{2} \cdot 5 \cdot 7 \)
Exponent: \(840\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \cdot 7 \)
Derived length:$1$

The ambient group is nonabelian, almost simple, nonsolvable, and rational.

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)$$\PSL(3,4):D_6$, of order \(241920\)\(\medspace = 2^{8} \cdot 3^{3} \cdot 5 \cdot 7 \)
$\operatorname{Aut}(H)$ $F_9:C_2^2$, of order \(288\)\(\medspace = 2^{5} \cdot 3^{2} \)
$W$$\PSU(3,2)$, of order \(72\)\(\medspace = 2^{3} \cdot 3^{2} \)
