Subgroup ($H$) information
| Description: | $C_3^3:A_4^2$ |
| Order: | \(3888\)\(\medspace = 2^{4} \cdot 3^{5} \) |
| Index: | \(8\)\(\medspace = 2^{3} \) |
| Exponent: | \(18\)\(\medspace = 2 \cdot 3^{2} \) |
| Generators: |
$\langle(7,12,15,8,11,13,9,10,14), (10,12,11), (7,8)(13,15), (1,2)(3,4)(11,12)(13,15) \!\cdots\! \rangle$
|
| Derived length: | $3$ |
The subgroup is the commutator subgroup (hence characteristic and normal), a semidirect factor, nonabelian, and monomial (hence solvable).
Ambient group ($G$) information
| Description: | $C_2\times C_3^3:S_4^2$ |
| Order: | \(31104\)\(\medspace = 2^{7} \cdot 3^{5} \) |
| Exponent: | \(36\)\(\medspace = 2^{2} \cdot 3^{2} \) |
| Derived length: | $4$ |
The ambient group is nonabelian and monomial (hence solvable).
Quotient group ($Q$) structure
| Description: | $C_2^3$ |
| Order: | \(8\)\(\medspace = 2^{3} \) |
| Exponent: | \(2\) |
| Automorphism Group: | $\PSL(2,7)$, of order \(168\)\(\medspace = 2^{3} \cdot 3 \cdot 7 \) |
| Outer Automorphisms: | $\PSL(2,7)$, of order \(168\)\(\medspace = 2^{3} \cdot 3 \cdot 7 \) |
| Derived length: | $1$ |
The quotient is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), a $p$-group (hence elementary and hyperelementary), 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 $W = G / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $C_2\times C_3^3.A_4^2.C_2^4$ |
| $\operatorname{Aut}(H)$ | $S_3\wr S_3\times S_4$, of order \(31104\)\(\medspace = 2^{7} \cdot 3^{5} \) |
| $W$ | $C_3^3:S_4^2$, of order \(15552\)\(\medspace = 2^{6} \cdot 3^{5} \) |
