Subgroup ($H$) information

Description:$C_3^2$
Order: \(9\)\(\medspace = 3^{2} \)
Index: \(1944\)\(\medspace = 2^{3} \cdot 3^{5} \)
Exponent: \(3\)
Generators: $\langle(1,18,11)(2,16,7)(3,8,17)(4,12,9)(5,13,10)(6,15,14), (2,16,7)(3,8,17)(6,15,14)\rangle$ 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), a $p$-group (hence elementary and hyperelementary), and metacyclic.

Ambient group ($G$) information

Description: $(C_3^3\times \He_3):D_{12}$
Order: \(17496\)\(\medspace = 2^{3} \cdot 3^{7} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Derived length:$3$

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

Quotient group ($Q$) structure

Description: $C_3^4:D_{12}$
Order: \(1944\)\(\medspace = 2^{3} \cdot 3^{5} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Automorphism Group: $C_3^5.C_2^2.C_2^4.C_2$, of order \(31104\)\(\medspace = 2^{7} \cdot 3^{5} \)
Outer Automorphisms: $C_2\times D_4$, of order \(16\)\(\medspace = 2^{4} \)
Nilpotency class: $-1$
Derived length: $3$

The quotient is nonabelian and solvable. Whether it is monomial has not been computed.

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_3^6.C_3.D_6^2.C_2^2$, of order \(1259712\)\(\medspace = 2^{6} \cdot 3^{9} \)
$\operatorname{Aut}(H)$ $\GL(2,3)$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \)
$W$$C_2^2$, of order \(4\)\(\medspace = 2^{2} \)
