Subgroup ($H$) information

Description:$C_6\times D_6$
Order: \(72\)\(\medspace = 2^{3} \cdot 3^{2} \)
Index: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $a^{3}, b^{4}, b^{6}, d^{3}, d^{2}$ Copy content Toggle raw display
Derived length: $2$

The subgroup is normal, a semidirect factor, nonabelian, supersolvable (hence solvable and monomial), metabelian, and an A-group.

Ambient group ($G$) information

Description: $C_6^2.S_3^2$
Order: \(1296\)\(\medspace = 2^{4} \cdot 3^{4} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_3\times S_3$
Order: \(18\)\(\medspace = 2 \cdot 3^{2} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Automorphism Group: $D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
Outer Automorphisms: $C_2$, of order \(2\)
Derived length: $2$

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

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)$$\PSU(3,2).C_6^2.C_2^6$

$\operatorname{res}(S)$$D_4\times D_6$, of order \(96\)\(\medspace = 2^{5} \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(432\)\(\medspace = 2^{4} \cdot 3^{3} \)
