Subgroup ($H$) information

Description:$C_3^3$
Order: \(27\)\(\medspace = 3^{3} \)
Index: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Exponent: \(3\)
Generators: $\left(\begin{array}{ll}\alpha^{115} & \alpha^{203} \\ \alpha^{182} & \alpha^{95} \\ \end{array}\right), \left(\begin{array}{ll}\alpha^{189} & \alpha^{196} \\ \alpha^{175} & \alpha^{241} \\ \end{array}\right), \left(\begin{array}{ll}\alpha^{88} & \alpha^{141} \\ \alpha^{120} & \alpha^{10} \\ \end{array}\right)$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

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

Ambient group ($G$) information

Description: $C_3^4:S_3$
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, an A-group, and rational.

Quotient group ($Q$) structure

Description: $C_3:S_3$
Order: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Automorphism Group: $C_3^2:\GL(2,3)$, of order \(432\)\(\medspace = 2^{4} \cdot 3^{3} \)
Outer Automorphisms: $S_4$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
Nilpotency class: $-1$
Derived length: $2$

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

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)$$\AGL(5,3)$, of order \(115562653240320\)\(\medspace = 2^{10} \cdot 3^{15} \cdot 5 \cdot 11^{2} \cdot 13 \)
$\operatorname{Aut}(H)$ $\GL(3,3)$, of order \(11232\)\(\medspace = 2^{5} \cdot 3^{3} \cdot 13 \)
$\operatorname{res}(S)$$\GL(3,3)$, of order \(11232\)\(\medspace = 2^{5} \cdot 3^{3} \cdot 13 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(8503056\)\(\medspace = 2^{4} \cdot 3^{12} \)
$W$$C_2$, of order \(2\)
