Subgroup ($H$) information

Description:$D_9\times S_3^2$
Order: \(648\)\(\medspace = 2^{3} \cdot 3^{4} \)
Index: \(162\)\(\medspace = 2 \cdot 3^{4} \)
Exponent: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Generators: $ad^{6}e^{8}, e^{3}, d^{3}e^{6}, c^{9}d^{7}e^{2}f^{8}, c^{6}e^{3}, b^{2}c^{4}e, c^{14}e^{7}$ Copy content Toggle raw display
Derived length: $2$

The subgroup is nonabelian, supersolvable (hence solvable and monomial), metabelian, and an A-group.

Ambient group ($G$) information

Description: $C_9^4:(C_2\times D_4)$
Order: \(104976\)\(\medspace = 2^{4} \cdot 3^{8} \)
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_9^4.(C_6\times D_4).C_6.C_2^3$, of order \(15116544\)\(\medspace = 2^{8} \cdot 3^{10} \)
$\operatorname{Aut}(H)$ $(D_9\times S_3^2):C_6$, of order \(3888\)\(\medspace = 2^{4} \cdot 3^{5} \)
$W$$D_9\times S_3^2$, of order \(648\)\(\medspace = 2^{3} \cdot 3^{4} \)
