Subgroup ($H$) information

Description:$C_3\times \He_3$
Order: \(81\)\(\medspace = 3^{4} \)
Index: \(9\)\(\medspace = 3^{2} \)
Exponent: \(3\)
Generators: $a, c, e$ Copy content Toggle raw display
Nilpotency class: $2$
Derived length: $2$

The subgroup is nonabelian, a $p$-group (hence nilpotent, solvable, supersolvable, monomial, elementary, and hyperelementary), and metabelian.

Ambient group ($G$) information

Description: $C_3^3:\He_3$
Order: \(729\)\(\medspace = 3^{6} \)
Exponent: \(3\)
Nilpotency class:$2$
Derived length:$2$

The ambient group is nonabelian, a $p$-group (hence nilpotent, solvable, supersolvable, monomial, elementary, and hyperelementary), and metabelian.

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_3^9.C_2.\SL(3,3)$, of order \(221079456\)\(\medspace = 2^{5} \cdot 3^{12} \cdot 13 \)
$\operatorname{Aut}(H)$ $C_3^4:(S_3\times \GL(2,3))$, of order \(23328\)\(\medspace = 2^{5} \cdot 3^{6} \)
$\operatorname{res}(S)$$C_3^3.S_3^3$, of order \(5832\)\(\medspace = 2^{3} \cdot 3^{6} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(81\)\(\medspace = 3^{4} \)
$W$$C_3^2$, of order \(9\)\(\medspace = 3^{2} \)
