Subgroup ($H$) information

Description:$C_2\times C_6$
Order: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Index: \(54\)\(\medspace = 2 \cdot 3^{3} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $c^{3}d^{3}, d^{3}, c^{2}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is characteristic (hence normal), abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), elementary for $p = 2$ (hence hyperelementary), and metacyclic.

Ambient group ($G$) information

Description: $C_3^3:S_4$
Order: \(648\)\(\medspace = 2^{3} \cdot 3^{4} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Derived length:$3$

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

Quotient group ($Q$) structure

Description: $C_3^2:C_6$
Order: \(54\)\(\medspace = 2 \cdot 3^{3} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Automorphism Group: $C_2\times C_3^2:\GL(2,3)$, of order \(864\)\(\medspace = 2^{5} \cdot 3^{3} \)
Outer Automorphisms: $C_2\times S_4$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \)
Nilpotency class: $-1$
Derived length: $2$

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

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)$$S_3\times C_6^2:D_6$, of order \(2592\)\(\medspace = 2^{5} \cdot 3^{4} \)
$\operatorname{Aut}(H)$ $D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
$\operatorname{res}(\operatorname{Aut}(G))$$D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(216\)\(\medspace = 2^{3} \cdot 3^{3} \)
$W$$S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \)
