Subgroup ($H$) information

Description:$\He_3$
Order: \(27\)\(\medspace = 3^{3} \)
Index: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
Exponent: \(3\)
Generators: $bde, cef$ 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: $(C_3^2\times \He_3):C_4$
Order: \(972\)\(\medspace = 2^{2} \cdot 3^{5} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
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:S_3.C_6^2.C_{12}.C_2^3$, of order \(62208\)\(\medspace = 2^{8} \cdot 3^{5} \)
$\operatorname{Aut}(H)$ $C_3^2:\GL(2,3)$, of order \(432\)\(\medspace = 2^{4} \cdot 3^{3} \)
$\operatorname{res}(S)$$F_9:C_2$, of order \(144\)\(\medspace = 2^{4} \cdot 3^{2} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(9\)\(\medspace = 3^{2} \)
$W$$C_3^2$, of order \(9\)\(\medspace = 3^{2} \)
