Subgroup ($H$) information

Description:$C_3^3$
Order: \(27\)\(\medspace = 3^{3} \)
Index: \(972\)\(\medspace = 2^{2} \cdot 3^{5} \)
Exponent: \(3\)
Generators: $\langle(1,7,4)(2,5,8)(10,15,16)(13,17,18)(19,27,22)(20,23,24), (2,5,8)(3,9,11) \!\cdots\! \rangle$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is normal, abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), and a $p$-group (hence elementary and hyperelementary). Whether it is a direct factor or a semidirect factor has not been computed.

Ambient group ($G$) information

Description: $C_3^6.D_{18}$
Order: \(26244\)\(\medspace = 2^{2} \cdot 3^{8} \)
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: $C_3^3:D_{18}$
Order: \(972\)\(\medspace = 2^{2} \cdot 3^{5} \)
Exponent: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Automorphism Group: $C_3^5.S_3^2$, of order \(8748\)\(\medspace = 2^{2} \cdot 3^{7} \)
Outer Automorphisms: $C_3^2$, of order \(9\)\(\medspace = 3^{2} \)
Nilpotency class: $-1$
Derived length: $3$

The quotient is nonabelian and supersolvable (hence solvable and monomial).

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)$$\GL(2,4):C_2^4$, of order \(25509168\)\(\medspace = 2^{4} \cdot 3^{13} \)
$\operatorname{Aut}(H)$ $\GL(3,3)$, of order \(11232\)\(\medspace = 2^{5} \cdot 3^{3} \cdot 13 \)
$\card{W}$ not computed
