Subgroup ($H$) information
| Description: | $C_2\times C_6$ | 
| Order: | \(12\)\(\medspace = 2^{2} \cdot 3 \) | 
| Index: | \(112\)\(\medspace = 2^{4} \cdot 7 \) | 
| Exponent: | \(6\)\(\medspace = 2 \cdot 3 \) | 
| Generators: | $d^{7}, b^{12}, b^{8}$ | 
| 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: | $C_{28}.(C_6\times D_4)$ | 
| Order: | \(1344\)\(\medspace = 2^{6} \cdot 3 \cdot 7 \) | 
| Exponent: | \(168\)\(\medspace = 2^{3} \cdot 3 \cdot 7 \) | 
| Derived length: | $2$ | 
The ambient group is nonabelian, supersolvable (hence solvable and monomial), and metabelian.
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 $W = N_G(H) / Z_G(H)$.
| $\operatorname{Aut}(G)$ | $C_7.(C_2^5\times C_6).C_2^3$ | 
| $\operatorname{Aut}(H)$ | $D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \) | 
| $\operatorname{res}(S)$ | $C_2$, of order \(2\) | 
| $\card{\operatorname{ker}(\operatorname{res})}$ | \(384\)\(\medspace = 2^{7} \cdot 3 \) | 
| $W$ | $C_2$, of order \(2\) |
