| Order: | \(32440320\)\(\medspace = 2^{16} \cdot 3^{2} \cdot 5 \cdot 11 \) |
| Index: | $1$ |
| Exponent: | \(2640\)\(\medspace = 2^{4} \cdot 3 \cdot 5 \cdot 11 \) |
| Generators: |
$\langle(1,20,5,23,2,19,6,24)(3,18,8,21,4,17,7,22)(9,12,10,11)(13,31,37,27)(14,32,38,28) \!\cdots\! \rangle$

| Derived length: | $1$ |
The subgroup is characteristic (hence normal), a semidirect factor, nonabelian, a Hall subgroup, and nonsolvable. Whether it is a direct factor has not been computed.
Ambient group ($G$) information
| Description: | $C_2^{12}.M_{11}$ |
| Order: | \(32440320\)\(\medspace = 2^{16} \cdot 3^{2} \cdot 5 \cdot 11 \) |
| Exponent: | \(2640\)\(\medspace = 2^{4} \cdot 3 \cdot 5 \cdot 11 \) |
| Derived length: | $1$ |
The ambient group is nonabelian and nonsolvable.
Quotient group ($Q$) structure
| Description: | $C_1$ |
| Order: | $1$ |
| Exponent: | $1$ |
| Automorphism Group: | $C_1$, of order $1$ |
| Outer Automorphisms: | $C_1$, of order $1$ |
| Derived length: | $0$ |
The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary (for every $p$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), a $p$-group (for every $p$), perfect, and rational.
Automorphism information
Since the subgroup $H$ is characteristic, the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : \operatorname{Aut}(G) \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphism group $\operatorname{Inn}(G)$ is the Weyl group $W = G / Z_G(H)$.
