Subgroup ($H$) information

Description:$C_3^4.C_6$
Order: \(486\)\(\medspace = 2 \cdot 3^{5} \)
Index: \(3\)
Exponent: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Generators: $e^{9}, e^{6}, de^{12}, b, e^{2}, c$ Copy content Toggle raw display
Nilpotency class: $2$
Derived length: $2$

The subgroup is characteristic (hence normal), maximal, a semidirect factor, nonabelian, elementary for $p = 3$ (hence nilpotent, solvable, supersolvable, monomial, and hyperelementary), and metabelian.

Ambient group ($G$) information

Description: $(C_3\times C_{18}):\He_3$
Order: \(1458\)\(\medspace = 2 \cdot 3^{6} \)
Exponent: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Nilpotency class:$3$
Derived length:$2$

The ambient group is nonabelian, elementary for $p = 3$ (hence nilpotent, solvable, supersolvable, monomial, and hyperelementary), and metabelian.

Quotient group ($Q$) structure

Description: $C_3$
Order: \(3\)
Exponent: \(3\)
Automorphism Group: $C_2$, of order \(2\)
Outer Automorphisms: $C_2$, of order \(2\)
Nilpotency class: $1$
Derived length: $1$

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

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_3^5.C_3^2.D_6$
$\operatorname{Aut}(H)$ $C_3^3.C_3^5:D_6$, of order \(78732\)\(\medspace = 2^{2} \cdot 3^{9} \)
$\card{\operatorname{res}(\operatorname{Aut}(G))}$\(2916\)\(\medspace = 2^{2} \cdot 3^{6} \)
$\card{\operatorname{ker}(\operatorname{res})}$\(9\)\(\medspace = 3^{2} \)
$W$$C_3\times \He_3$, of order \(81\)\(\medspace = 3^{4} \)
