| Order: | \(1185408\)\(\medspace = 2^{7} \cdot 3^{3} \cdot 7^{3} \) |
| Index: | $1$ |
| Exponent: | \(84\)\(\medspace = 2^{2} \cdot 3 \cdot 7 \) |
| Generators: |
$e^{21}f^{7}g^{7}, ad^{4}e^{39}fg^{11}, b^{3}, f^{2}g^{12}, c, b^{2}cd^{4}e^{9}f^{5}g^{4}, d^{3}e^{27}f^{7}g^{5}, g^{7}, d^{2}e^{18}f^{12}g^{2}, f^{7}, e^{14}f^{4}g^{10}, e^{6}f^{10}g^{8}, g^{2}$

| Derived length: | $4$ |
The subgroup is characteristic (hence normal), a semidirect factor, nonabelian, a Hall subgroup, and solvable. Whether it is a direct factor or monomial has not been computed.
Ambient group ($G$) information
| Description: | $D_7^3.C_6^2:D_6$ |
| Order: | \(1185408\)\(\medspace = 2^{7} \cdot 3^{3} \cdot 7^{3} \) |
| Exponent: | \(84\)\(\medspace = 2^{2} \cdot 3 \cdot 7 \) |
| Derived length: | $4$ |
The ambient group is nonabelian and solvable. Whether it is monomial has not been computed.
Quotient group ($Q$) structure
| Description: | $C_1$ |
| 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 $W = G / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $C_7^3.C_2^4:\He_3.C_6.C_2^4$ |
| $\operatorname{Aut}(H)$ | $C_7^3.C_2^4:\He_3.C_6.C_2^4$ |
| $\card{W}$ | not computed |
