Subgroup ($H$) information

Description:$C_2^2$
Order: \(4\)\(\medspace = 2^{2} \)
Index: \(1944\)\(\medspace = 2^{3} \cdot 3^{5} \)
Exponent: \(2\)
Generators: $\langle(1,2)(3,4)(6,7)(8,9), (1,4)(2,3)(8,9)\rangle$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), a $p$-group (hence elementary and hyperelementary), metacyclic, and rational.

Ambient group ($G$) information

Description: $C_6^3:S_3^2$
Order: \(7776\)\(\medspace = 2^{5} \cdot 3^{5} \)
Exponent: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
Derived length:$3$

The ambient group is nonabelian and monomial (hence solvable).

Automorphism information

While the subgroup $H$ is not characteristic, the stabilizer $S$ of $H$ in the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : S \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphisms $\operatorname{Inn}(G) \cap S$ is the Weyl group $W = N_G(H) / Z_G(H)$.

$\operatorname{Aut}(G)$$C_2\times C_6^2.C_3^4.C_2^4$
$\operatorname{Aut}(H)$ $S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \)
$W$$C_1$, of order $1$
