| Derived length: | not computed |
The subgroup is nonabelian and perfect (hence nonsolvable). Whether it is elementary, hyperelementary, monomial, simple, quasisimple, perfect, almost simple, or rational has not been computed.
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 \(24261120\)\(\medspace = 2^{9} \cdot 3^{6} \cdot 5 \cdot 13 \) |
| $\operatorname{Aut}(H)$ | not computed |
| $\card{W}$ | \(5616\)\(\medspace = 2^{4} \cdot 3^{3} \cdot 13 \) |
