Subgroup ($H$) information

Description:$C_3$
Order: \(3\)
Index: \(648\)\(\medspace = 2^{3} \cdot 3^{4} \)
Exponent: \(3\)
Generators: $f$ Copy content Toggle raw display

The subgroup is the center (hence characteristic, normal, abelian, central, nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), the Frattini subgroup, the socle, cyclic (hence elementary, hyperelementary, metacyclic, and a Z-group), stem, a $p$-group, and simple.

Ambient group ($G$) information

Description: $\Unitary(3,2):C_3$
Order: \(1944\)\(\medspace = 2^{3} \cdot 3^{5} \)
Exponent: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
Derived length:$5$

The ambient group is nonabelian and solvable.

Quotient group ($Q$) structure

Description: $C_3^3:\SL(2,3)$
Order: \(648\)\(\medspace = 2^{3} \cdot 3^{4} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Automorphism Group: $S_3\times C_3^2:\GL(2,3)$, of order \(2592\)\(\medspace = 2^{5} \cdot 3^{4} \)
Outer Automorphisms: $D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
Nilpotency class: $-1$
Derived length: $4$

The quotient is nonabelian and solvable.

Automorphism information

Since the subgroup $H$ is characteristic, the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : \operatorname{Aut}(G) \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphism group $\operatorname{Inn}(G)$ is the Weyl group $W = G / Z_G(H)$.

$\operatorname{Aut}(H)$ $C_2$, of order \(2\)
$\operatorname{res}(\operatorname{Aut}(G))$$C_1$, of order $1$
$\card{\operatorname{ker}(\operatorname{res})}$\(1944\)\(\medspace = 2^{3} \cdot 3^{5} \)
$W$$C_1$, of order $1$
