Subgroup ($H$) information

Description:$C_3^4$
Order: \(81\)\(\medspace = 3^{4} \)
Index: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Exponent: \(3\)
Generators: $b, c, ef, f$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group) and a $p$-group (hence elementary and hyperelementary).

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 \(62208\)\(\medspace = 2^{8} \cdot 3^{5} \)
$\operatorname{Aut}(H)$ $C_2.\PSL(4,3).C_2$, of order \(24261120\)\(\medspace = 2^{9} \cdot 3^{6} \cdot 5 \cdot 13 \)
$\operatorname{res}(S)$$D_6\times \GL(2,3)$, of order \(576\)\(\medspace = 2^{6} \cdot 3^{2} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(27\)\(\medspace = 3^{3} \)
$W$$S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \)
