Subgroup ($H$) information
| Description: | $C_7^3$ |
| Order: | \(343\)\(\medspace = 7^{3} \) |
| Index: | \(37044\)\(\medspace = 2^{2} \cdot 3^{3} \cdot 7^{3} \) |
| Exponent: | \(7\) |
| Generators: |
$eh^{4}i^{6}, gh^{6}i^{3}, fh^{6}$
|
| Nilpotency class: | $1$ |
| Derived length: | $1$ |
The subgroup is characteristic (hence normal), abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), and a $p$-group (hence elementary and hyperelementary). Whether it is a direct factor or a semidirect factor has not been computed.
Ambient group ($G$) information
| Description: | $C_7^6.C_3^2.D_6$ |
| Order: | \(12706092\)\(\medspace = 2^{2} \cdot 3^{3} \cdot 7^{6} \) |
| Exponent: | \(42\)\(\medspace = 2 \cdot 3 \cdot 7 \) |
| Derived length: | $4$ |
The ambient group is nonabelian and solvable. Whether it is monomial has not been computed.
Quotient group ($Q$) structure
| Description: | $C_7^3:C_3^2:D_6$ |

| Exponent: | \(42\)\(\medspace = 2 \cdot 3 \cdot 7 \) |
| Automorphism Group: | $C_2\times C_7^3.\He_3.Q_8.C_6$ |
| Outer Automorphisms: | $C_2\times \SL(2,3)$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \) |
| Nilpotency class: | $-1$ |
| Derived length: | $4$ |
The quotient is nonabelian and solvable. 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 $W = G / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $C_7^6.\He_3.Q_8.C_6^2$ |
| $\operatorname{Aut}(H)$ | $\GL(3,7)$, of order \(33784128\)\(\medspace = 2^{6} \cdot 3^{4} \cdot 7^{3} \cdot 19 \) |
| $\card{W}$ | not computed |
