Subgroup ($H$) information

Description:$S_3$
Order: \(6\)\(\medspace = 2 \cdot 3 \)
Index: \(64\)\(\medspace = 2^{6} \)
Exponent: \(6\)\(\medspace = 2 \cdot 3 \)
Generators: $\left(\begin{array}{rr} 8 & 36 \\ 11 & 43 \end{array}\right), \left(\begin{array}{rr} 25 & 36 \\ 6 & 25 \end{array}\right)$ Copy content Toggle raw display
Derived length: $2$

The subgroup is nonabelian, a Z-group (hence solvable, supersolvable, monomial, metacyclic, metabelian, and an A-group), hyperelementary for $p = 2$, and rational.

Ambient group ($G$) information

Description: $\GL(2,3):D_4$
Order: \(384\)\(\medspace = 2^{7} \cdot 3 \)
Exponent: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Derived length:$4$

The ambient group is nonabelian and solvable.

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_2^6\times S_4$, of order \(1536\)\(\medspace = 2^{9} \cdot 3 \)
$\operatorname{Aut}(H)$ $S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \)
$\operatorname{res}(S)$$S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(16\)\(\medspace = 2^{4} \)
$W$$S_3$, of order \(6\)\(\medspace = 2 \cdot 3 \)
