Subgroup ($H$) information
| Description: | $C_2^8$ |
| Order: | \(256\)\(\medspace = 2^{8} \) |
| Index: | \(10368\)\(\medspace = 2^{7} \cdot 3^{4} \) |
| Exponent: | \(2\) |
| Generators: |
$\langle(1,2)(7,8)(9,10)(13,14)(15,16)(21,22), (3,4)(7,8)(15,16)(19,20), (7,8)(15,16) \!\cdots\! \rangle$
|
| Nilpotency class: | $1$ |
| Derived length: | $1$ |
The subgroup is characteristic (hence normal), abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), a $p$-group (hence elementary and hyperelementary), and rational. Whether it is a direct factor or a semidirect factor has not been computed.
Ambient group ($G$) information
| Description: | $C_2^{10}.(C_2\times S_3^2:S_3^2)$ |
| Order: | \(2654208\)\(\medspace = 2^{15} \cdot 3^{4} \) |
| Exponent: | \(24\)\(\medspace = 2^{3} \cdot 3 \) |
| Derived length: | $4$ |
The ambient group is nonabelian, solvable, and rational. Whether it is monomial has not been computed.
Quotient group ($Q$) structure
| Description: | $C_6^3.(S_3\times D_4)$ |

| Exponent: | \(24\)\(\medspace = 2^{3} \cdot 3 \) |
| Automorphism Group: | $C_3^4.C_2^6.C_2^6$ |
| Outer Automorphisms: | $D_4\times C_2^3$, of order \(64\)\(\medspace = 2^{6} \) |
| Nilpotency class: | $-1$ |
| Derived length: | $3$ |
The quotient is nonabelian, solvable, and rational. Whether it is monomial has not been computed.
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 $W = G / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $C_2^8.C_3^4.C_2^6.C_2^5$ |
| $\operatorname{Aut}(H)$ | $\GL(8,2)$ |
| $W$ | $S_3^2:S_3^2$, of order \(1296\)\(\medspace = 2^{4} \cdot 3^{4} \) |
