Subgroup ($H$) information

Description:$C_3^3$
Order: \(27\)\(\medspace = 3^{3} \)
Index: \(108\)\(\medspace = 2^{2} \cdot 3^{3} \)
Exponent: \(3\)
Generators: $cf^{6}, ef^{3}, f^{3}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

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

Ambient group ($G$) information

Description: $C_3^4:S_3^2$
Order: \(2916\)\(\medspace = 2^{2} \cdot 3^{6} \)
Exponent: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Derived length:$3$

The ambient group is nonabelian and supersolvable (hence solvable and monomial).

Quotient group ($Q$) structure

Description: $C_3:S_3^2$
Order: \(108\)\(\medspace = 2^{2} \cdot 3^{3} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Automorphism Group: $S_3\times C_3^2:\GL(2,3)$, of order \(2592\)\(\medspace = 2^{5} \cdot 3^{4} \)
Outer Automorphisms: $S_4$, 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

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}(G)$$C_3^3.S_3^3$, of order \(5832\)\(\medspace = 2^{3} \cdot 3^{6} \)
$\operatorname{Aut}(H)$ $\GL(3,3)$, of order \(11232\)\(\medspace = 2^{5} \cdot 3^{3} \cdot 13 \)
$\operatorname{res}(\operatorname{Aut}(G))$$S_3\times D_6$, of order \(72\)\(\medspace = 2^{3} \cdot 3^{2} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(81\)\(\medspace = 3^{4} \)
$W$$S_3^2$, of order \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
