Subgroup ($H$) information
| Description: | not computed |
| Order: | \(11496038400\)\(\medspace = 2^{13} \cdot 3^{6} \cdot 5^{2} \cdot 7 \cdot 11 \) |
| Index: | \(278460\)\(\medspace = 2^{2} \cdot 3^{2} \cdot 5 \cdot 7 \cdot 13 \cdot 17 \) |
| Exponent: | not computed |
| Generators: |
$\langle(3,4,5,6)(7,8), (3,5,6), (3,6,5,4)(7,8,9,10,11,12,13,14,15,16,17,18), (3,5) \!\cdots\! \rangle$

| Derived length: | not computed |
The subgroup is nonabelian and nonsolvable. Whether it is elementary, hyperelementary, monomial, simple, quasisimple, perfect, almost simple, or rational has not been computed.
Ambient group ($G$) information
| Description: | $A_{18}$ |
| Order: | \(3201186852864000\)\(\medspace = 2^{15} \cdot 3^{8} \cdot 5^{3} \cdot 7^{2} \cdot 11 \cdot 13 \cdot 17 \) |
| Exponent: | \(12252240\)\(\medspace = 2^{4} \cdot 3^{2} \cdot 5 \cdot 7 \cdot 11 \cdot 13 \cdot 17 \) |
| 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 $W = N_G(H) / Z_G(H)$.
