| Derived length: | $2$ |
The subgroup is nonabelian, metacyclic (hence solvable, supersolvable, monomial, and metabelian), hyperelementary for $p = 2$, and an A-group.
Ambient group ($G$) information
| Description: | $\PSL(2,1849)$ |
| Order: | \(3160680600\)\(\medspace = 2^{3} \cdot 3 \cdot 5^{2} \cdot 7 \cdot 11 \cdot 37 \cdot 43^{2} \) |
| Exponent: | \(36752100\)\(\medspace = 2^{2} \cdot 3 \cdot 5^{2} \cdot 7 \cdot 11 \cdot 37 \cdot 43 \) |
| Derived length: | $0$ |
The ambient group is nonabelian and simple (hence nonsolvable, perfect, quasisimple, and almost simple).
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 $W = N_G(H) / Z_G(H)$.
