Subgroup ($H$) information

Description:$C_9$
Order: \(9\)\(\medspace = 3^{2} \)
Index: \(324\)\(\medspace = 2^{2} \cdot 3^{4} \)
Exponent: \(9\)\(\medspace = 3^{2} \)
Generators: $cd^{4}e^{5}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

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

Ambient group ($G$) information

Description: $C_9^2.S_3^2$
Order: \(2916\)\(\medspace = 2^{2} \cdot 3^{6} \)
Exponent: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Derived length:$3$

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

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 $W = N_G(H) / Z_G(H)$.
