Subgroup ($H$) information

Description:$C_3^2:C_6$
Order: \(54\)\(\medspace = 2 \cdot 3^{3} \)
Index: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $b^{3}, b^{2}, c^{3}, d^{2}$ 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: $C_2\times C_3^2:D_{18}$
Order: \(648\)\(\medspace = 2^{3} \cdot 3^{4} \)
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 $W = N_G(H) / Z_G(H)$.

$\operatorname{Aut}(G)$$C_2\times C_3^4.C_3.C_2^3$
$\operatorname{Aut}(H)$ $C_2\times C_3^2:\GL(2,3)$, of order \(864\)\(\medspace = 2^{5} \cdot 3^{3} \)
$\operatorname{res}(S)$$S_3^2$, of order \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(18\)\(\medspace = 2 \cdot 3^{2} \)
$W$$S_3^2$, of order \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
