Subgroup ($H$) information

Description:$C_9^2:D_6$
Order: \(972\)\(\medspace = 2^{2} \cdot 3^{5} \)
Index: \(108\)\(\medspace = 2^{2} \cdot 3^{3} \)
Exponent: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Generators: $c^{9}, d^{3}e^{6}f^{6}, c^{6}, b^{2}c^{4}e, f^{3}, de^{8}f^{5}, d^{6}e^{3}f^{7}$ 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 \(15116544\)\(\medspace = 2^{8} \cdot 3^{10} \)
$\operatorname{Aut}(H)$ $S_3\times C_9^2.C_3^3.Q_8.C_3.C_6$, of order \(1889568\)\(\medspace = 2^{5} \cdot 3^{10} \)
$W$$S_3\times D_9^2$, of order \(1944\)\(\medspace = 2^{3} \cdot 3^{5} \)
