Index: | \(24\)\(\medspace = 2^{3} \cdot 3 \) |
Exponent: | \(8\)\(\medspace = 2^{3} \) |

$\left(\begin{array}{rr}
13 & 8 \\
24 & 21
\end{array}\right), \left(\begin{array}{rr}

Nilpotency class: | $1$ |
Derived length: | $1$ |
The subgroup is normal, abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), and a $p$-group (hence elementary and hyperelementary).
Ambient group ($G$) information
Description: | $C_2^4:C_{48}$ |
Order: | \(768\)\(\medspace = 2^{8} \cdot 3 \) |
Exponent: | \(48\)\(\medspace = 2^{4} \cdot 3 \) |
Derived length: | $2$ |
The ambient group is nonabelian, monomial (hence solvable), metabelian, and an A-group.
Quotient group ($Q$) structure
Description: | $C_2\times C_{12}$ |
Order: | \(24\)\(\medspace = 2^{3} \cdot 3 \) |
Exponent: | \(12\)\(\medspace = 2^{2} \cdot 3 \) |
Automorphism Group: | $C_2\times D_4$, of order \(16\)\(\medspace = 2^{4} \) |
Outer Automorphisms: | $C_2\times D_4$, of order \(16\)\(\medspace = 2^{4} \) |
Nilpotency class: | $1$ |
Derived length: | $1$ |
The quotient is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), elementary for $p = 2$ (hence 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 $W = N_G(H) / Z_G(H)$.
$\operatorname{Aut}(G)$ | $C_2.C_2^6.D_6^2$ |
$\operatorname{Aut}(H)$ | $C_2^4:S_4$, of order \(384\)\(\medspace = 2^{7} \cdot 3 \) |
$\operatorname{res}(S)$ | $C_2\times D_6$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \) |
$\card{\operatorname{ker}(\operatorname{res})}$ | \(256\)\(\medspace = 2^{8} \) |
$W$ | $C_3$, of order \(3\) |
