Subgroup ($H$) information

Description:$C_{12}.C_{24}$
Order: \(288\)\(\medspace = 2^{5} \cdot 3^{2} \)
Index: \(16\)\(\medspace = 2^{4} \)
Exponent: \(48\)\(\medspace = 2^{4} \cdot 3 \)
Generators: $\left(\begin{array}{rr} 1 & 0 \\ 0 & 85 \end{array}\right), \left(\begin{array}{rr} 84 & 0 \\ 0 & 108 \end{array}\right), \left(\begin{array}{rr} 85 & 0 \\ 0 & 109 \end{array}\right), \left(\begin{array}{rr} 1 & 0 \\ 0 & 84 \end{array}\right), \left(\begin{array}{rr} 0 & 46 \\ 190 & 0 \end{array}\right), \left(\begin{array}{rr} 186 & 0 \\ 0 & 186 \end{array}\right), \left(\begin{array}{rr} 49 & 0 \\ 0 & 130 \end{array}\right)$ Copy content Toggle raw display
Derived length: $2$

The subgroup is normal, nonabelian, and metacyclic (hence solvable, supersolvable, monomial, and metabelian).

Ambient group ($G$) information

Description: $D_{24}.C_{96}$
Order: \(4608\)\(\medspace = 2^{9} \cdot 3^{2} \)
Exponent: \(192\)\(\medspace = 2^{6} \cdot 3 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_2\times C_8$
Order: \(16\)\(\medspace = 2^{4} \)
Exponent: \(8\)\(\medspace = 2^{3} \)
Automorphism Group: $C_2\times D_4$, of order \(16\)\(\medspace = 2^{4} \)
Outer Automorphisms: $C_2\times D_4$, of order \(16\)\(\medspace = 2^{4} \)
Derived length: $1$

The quotient is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), a $p$-group (hence elementary and hyperelementary), and metacyclic.

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)$$C_3:((C_4\times C_8).C_2^6.C_2)$
$\operatorname{Aut}(H)$ $D_{12}:C_2^4$, of order \(384\)\(\medspace = 2^{7} \cdot 3 \)
$\operatorname{res}(S)$$D_{12}:C_2^4$, of order \(384\)\(\medspace = 2^{7} \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(16\)\(\medspace = 2^{4} \)
$W$$D_{12}$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
