Derived length: $4$

The subgroup is nonabelian and monomial (hence solvable).

Ambient group ($G$) information

Description: $\PGL(4,3)$
Order: \(12130560\)\(\medspace = 2^{8} \cdot 3^{6} \cdot 5 \cdot 13 \)
Exponent: \(4680\)\(\medspace = 2^{3} \cdot 3^{2} \cdot 5 \cdot 13 \)
Derived length:$1$

The ambient group is nonabelian, almost simple, 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)$$\PSL(4,3).C_2^2$, of order \(24261120\)\(\medspace = 2^{9} \cdot 3^{6} \cdot 5 \cdot 13 \)
$\operatorname{Aut}(H)$ $S_3\wr S_3$, of order \(1296\)\(\medspace = 2^{4} \cdot 3^{4} \)
$\card{W}$\(1296\)\(\medspace = 2^{4} \cdot 3^{4} \)
