Subgroup ($H$) information

Description:$C_3^3$
Order: \(27\)\(\medspace = 3^{3} \)
Index: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Exponent: \(3\)
Generators: $\left(\begin{array}{rr} 13 & 0 \\ 0 & 1 \end{array}\right), \left(\begin{array}{rr} 13 & 0 \\ 0 & 13 \end{array}\right), \left(\begin{array}{rr} 4 & 3 \\ 15 & 13 \end{array}\right)$ 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: $S_3\times C_3^4$
Order: \(486\)\(\medspace = 2 \cdot 3^{5} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Derived length:$2$

The ambient group is nonabelian, supersolvable (hence solvable and monomial), metabelian, and an A-group.

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.\PSL(4,3).C_2\times S_3$, of order \(145566720\)\(\medspace = 2^{10} \cdot 3^{7} \cdot 5 \cdot 13 \)
$\operatorname{Aut}(H)$ $\GL(3,3)$, of order \(11232\)\(\medspace = 2^{5} \cdot 3^{3} \cdot 13 \)
$\operatorname{res}(S)$$C_2\times C_3^2:\GL(2,3)$, of order \(864\)\(\medspace = 2^{5} \cdot 3^{3} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(162\)\(\medspace = 2 \cdot 3^{4} \)
$W$$C_1$, of order $1$
