Subgroup ($H$) information

Description:$C_3$
Order: \(3\)
Index: \(243\)\(\medspace = 3^{5} \)
Exponent: \(3\)
Generators: $c$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is normal, a direct factor, cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), central, a $p$-group, and simple.

Ambient group ($G$) information

Description: $C_3^4\times C_9$
Order: \(729\)\(\medspace = 3^{6} \)
Exponent: \(9\)\(\medspace = 3^{2} \)
Nilpotency class:$1$
Derived length:$1$

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

Quotient group ($Q$) structure

Description: $C_3^3\times C_9$
Order: \(243\)\(\medspace = 3^{5} \)
Exponent: \(9\)\(\medspace = 3^{2} \)
Automorphism Group: $C_3^4.(C_2\times C_3^3:\GL(3,3))$, of order \(49128768\)\(\medspace = 2^{6} \cdot 3^{10} \cdot 13 \)
Outer Automorphisms: $C_3^4.(C_2\times C_3^3:\GL(3,3))$, of order \(49128768\)\(\medspace = 2^{6} \cdot 3^{10} \cdot 13 \)
Nilpotency class: $1$
Derived length: $1$

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

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_3^5.C_3^4.C_2^2.\PSL(4,3).C_2$, of order \(955063249920\)\(\medspace = 2^{10} \cdot 3^{15} \cdot 5 \cdot 13 \)
$\operatorname{Aut}(H)$ $C_2$, of order \(2\)
$\operatorname{res}(S)$$C_2$, of order \(2\)
$\card{\operatorname{ker}(\operatorname{res})}$\(3979430208\)\(\medspace = 2^{6} \cdot 3^{14} \cdot 13 \)
$W$$C_1$, of order $1$
