Subgroup ($H$) information

Description:$C_6$
Order: \(6\)\(\medspace = 2 \cdot 3 \)
Index: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $\left(\begin{array}{rr} 8 & 0 \\ 0 & 8 \end{array}\right), \left(\begin{array}{rr} 7 & 0 \\ 3 & 4 \end{array}\right)$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is normal and cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,3$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).

Ambient group ($G$) information

Description: $C_3^2:D_{12}$
Order: \(216\)\(\medspace = 2^{3} \cdot 3^{3} \)
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: $S_3^2$
Order: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Automorphism Group: $\SOPlus(4,2)$, of order \(72\)\(\medspace = 2^{3} \cdot 3^{2} \)
Outer Automorphisms: $C_2$, of order \(2\)
Nilpotency class: $-1$
Derived length: $2$

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

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)$$D_6^2:D_6$, of order \(1728\)\(\medspace = 2^{6} \cdot 3^{3} \)
$\operatorname{Aut}(H)$ $C_2$, of order \(2\)
$\operatorname{res}(S)$$C_2$, of order \(2\)
$\card{\operatorname{ker}(\operatorname{res})}$\(432\)\(\medspace = 2^{4} \cdot 3^{3} \)
$W$$C_2$, of order \(2\)
