| Order: | \(112\)\(\medspace = 2^{4} \cdot 7 \) |
| Index: | \(1092\)\(\medspace = 2^{2} \cdot 3 \cdot 7 \cdot 13 \) |
| Exponent: | \(56\)\(\medspace = 2^{3} \cdot 7 \) |
| Generators: |
$\left(\begin{array}{ll}\alpha^{48} & 0 \\ 0 & \alpha^{48} \\ \end{array}\right), \left(\begin{array}{ll}\alpha^{132} & 0 \\ 0 & \alpha^{132} \\ \end{array}\right), \left(\begin{array}{ll}\alpha^{150} & 0 \\ 0 & \alpha^{150} \\ \end{array}\right), \left(\begin{array}{ll}\alpha^{39} & \alpha^{42} \\ \alpha^{26} & \alpha^{123} \\ \end{array}\right), \left(\begin{array}{ll}\alpha^{159} & 0 \\ 0 & \alpha^{159} \\ \end{array}\right)$

| Nilpotency class: | $1$ |
| Derived length: | $1$ |
The subgroup is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), elementary for $p = 2$ (hence hyperelementary), and metacyclic.
Ambient group ($G$) information
| Description: | $C_{56}.\PGL(2,13)$ |
| Order: | \(122304\)\(\medspace = 2^{6} \cdot 3 \cdot 7^{2} \cdot 13 \) |
| Exponent: | \(2184\)\(\medspace = 2^{3} \cdot 3 \cdot 7 \cdot 13 \) |
| Derived length: | $1$ |
The ambient group is nonabelian and nonsolvable.
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 $W = N_G(H) / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $C_2^3\times C_6\times \PSL(2,13).C_2$, of order \(104832\)\(\medspace = 2^{7} \cdot 3^{2} \cdot 7 \cdot 13 \) |
| $\operatorname{Aut}(H)$ | $C_{12}:C_2^3$, of order \(96\)\(\medspace = 2^{5} \cdot 3 \) |
| $W$ | $C_2$, of order \(2\) |
