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: | $\langle(1,22)(2,42)(3,23)(4,32)(5,37)(6,40)(7,30)(8,25)(9,38)(10,39)(11,31)(12,26) \!\cdots\! \rangle$ |
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 \(72\)\(\medspace = 2^{3} \cdot 3^{2} \) |
