Subgroup ($H$) information

Description:$(C_3\times \He_3):C_4$
Order: \(324\)\(\medspace = 2^{2} \cdot 3^{4} \)
Index: \(9\)\(\medspace = 3^{2} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $\langle(11,16,12)(14,17,18), (10,13,15)(11,12,16)(14,17,18), (10,17,16)(11,13,18) \!\cdots\! \rangle$ Copy content Toggle raw display
Derived length: $3$

The subgroup is maximal, nonabelian, and supersolvable (hence solvable and monomial).

Ambient group ($G$) information

Description: $(C_3^3\times \He_3):C_4$
Order: \(2916\)\(\medspace = 2^{2} \cdot 3^{6} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Derived length:$3$

The ambient group is nonabelian and monomial (hence solvable).

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)$$\He_3:(C_3:S_3).C_6^2.C_{12}.C_2^4$, of order \(3359232\)\(\medspace = 2^{9} \cdot 3^{8} \)
$\operatorname{Aut}(H)$ $C_2\times C_3^3:C_3^2.Q_8.D_6$, of order \(46656\)\(\medspace = 2^{6} \cdot 3^{6} \)
$\card{\operatorname{res}(S)}$\(46656\)\(\medspace = 2^{6} \cdot 3^{6} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(8\)\(\medspace = 2^{3} \)
$W$$C_3^2:S_3$, of order \(54\)\(\medspace = 2 \cdot 3^{3} \)
