Subgroup ($H$) information

Description:$C_3^2$
Order: \(9\)\(\medspace = 3^{2} \)
Index: \(1944\)\(\medspace = 2^{3} \cdot 3^{5} \)
Exponent: \(3\)
Generators: $\langle(1,18,11)(2,16,7)(3,8,17)(4,12,9)(5,13,10)(6,15,14)(20,22,24), (2,7,16)(3,17,8)(4,12,9)(5,10,13)(6,14,15)(19,23,21)\rangle$ 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), and metacyclic.

Ambient group ($G$) information

Description: $(C_3^3\times \He_3):D_{12}$
Order: \(17496\)\(\medspace = 2^{3} \cdot 3^{7} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
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_3^6.C_3.D_6^2.C_2^2$, of order \(1259712\)\(\medspace = 2^{6} \cdot 3^{9} \)
$\operatorname{Aut}(H)$ $\GL(2,3)$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \)
$W$$C_1$, of order $1$
