Derived length: not computed

The subgroup is nonabelian and supersolvable (hence solvable and monomial). Whether it is elementary, hyperelementary, monomial, simple, quasisimple, perfect, almost simple, or rational has not been computed.

Ambient group ($G$) information

Description: $\PGL(3,19)$
Order: \(16934047920\)\(\medspace = 2^{4} \cdot 3^{5} \cdot 5 \cdot 19^{3} \cdot 127 \)
Exponent: \(868680\)\(\medspace = 2^{3} \cdot 3^{2} \cdot 5 \cdot 19 \cdot 127 \)
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 $W = N_G(H) / Z_G(H)$.
