Subgroup ($H$) information

Description:$Q_8\times C_{14}$
Order: \(112\)\(\medspace = 2^{4} \cdot 7 \)
Index: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Exponent: \(28\)\(\medspace = 2^{2} \cdot 7 \)
Generators: $bc^{21}, c^{6}, d^{2}, d^{7}, c^{12}$ Copy content Toggle raw display
Nilpotency class: $2$
Derived length: $2$

The subgroup is nonabelian, elementary for $p = 2$ (hence nilpotent, solvable, supersolvable, monomial, and hyperelementary), and metabelian.

Ambient group ($G$) information

Description: $D_{56}.D_6$
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), hyperelementary for $p = 2$, 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_2\times C_{84}).C_6.C_2^6$
$\operatorname{Aut}(H)$ $C_6\times C_2^3:S_4$, of order \(1152\)\(\medspace = 2^{7} \cdot 3^{2} \)
$\card{W}$\(16\)\(\medspace = 2^{4} \)
