Subgroup ($H$) information

Description:$C_3^2$
Order: \(9\)\(\medspace = 3^{2} \)
Index: \(2304\)\(\medspace = 2^{8} \cdot 3^{2} \)
Exponent: \(3\)
Generators: $\langle(10,14,13), (9,11,12)(10,14,13)\rangle$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is characteristic (hence normal), a semidirect factor, 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: $(S_3^2\times A_4^2):C_2^2$
Order: \(20736\)\(\medspace = 2^{8} \cdot 3^{4} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Derived length:$3$

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

Quotient group ($Q$) structure

Description: $C_2\times A_4^2:D_4$
Order: \(2304\)\(\medspace = 2^{8} \cdot 3^{2} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Automorphism Group: $A_4^2.C_2^4.C_2^3$
Outer Automorphisms: $C_2^2\times D_4$, of order \(32\)\(\medspace = 2^{5} \)
Nilpotency class: $-1$
Derived length: $3$

The quotient is nonabelian and monomial (hence solvable).

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_3^2.A_4^2.C_2.C_2^6$
$\operatorname{Aut}(H)$ $\GL(2,3)$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \)
$W$$D_4$, of order \(8\)\(\medspace = 2^{3} \)
