Subgroup ($H$) information

Description:$C_9^2:C_9$
Order: \(729\)\(\medspace = 3^{6} \)
Index: \(432\)\(\medspace = 2^{4} \cdot 3^{3} \)
Exponent: \(9\)\(\medspace = 3^{2} \)
Generators: $b^{2}d^{2}e^{7}f^{7}, cd^{4}e^{3}f^{6}, e^{4}f^{7}$ 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: $C_9^4.C_6.D_4$
Order: \(314928\)\(\medspace = 2^{4} \cdot 3^{9} \)
Exponent: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
Derived length:$3$

The ambient group is nonabelian and solvable. Whether it is monomial has not been computed.

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_3^7.S_3\wr C_2^2$, of order \(11337408\)\(\medspace = 2^{6} \cdot 3^{11} \)
$\operatorname{Aut}(H)$ $C_3^8.C_3:S_3.C_6.C_2$, of order \(1417176\)\(\medspace = 2^{3} \cdot 3^{11} \)
$\card{W}$\(81\)\(\medspace = 3^{4} \)
