Subgroup ($H$) information

Description:$C_3\times C_9$
Order: \(27\)\(\medspace = 3^{3} \)
Index: \(864\)\(\medspace = 2^{5} \cdot 3^{3} \)
Exponent: \(9\)\(\medspace = 3^{2} \)
Generators: $\langle(1,3,2)(4,6,5)(7,9,8)(10,12,11)(13,15,14)(16,18,17)(19,21,20)(22,24,23) \!\cdots\! \rangle$ 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: $C_3^3:S_3^2.S_4$
Order: \(23328\)\(\medspace = 2^{5} \cdot 3^{6} \)
Exponent: \(72\)\(\medspace = 2^{3} \cdot 3^{2} \)
Derived length:$6$

The ambient group is nonabelian and 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_3^3:\SOPlus(4,2).S_4$, of order \(46656\)\(\medspace = 2^{6} \cdot 3^{6} \)
$\operatorname{Aut}(H)$ $C_3^2:D_6$, of order \(108\)\(\medspace = 2^{2} \cdot 3^{3} \)
$W$$C_3\times S_3$, of order \(18\)\(\medspace = 2 \cdot 3^{2} \)
