Subgroup ($H$) information

Description:$C_7:Q_{16}$
Order: \(112\)\(\medspace = 2^{4} \cdot 7 \)
Index: \(5\)
Exponent: \(56\)\(\medspace = 2^{3} \cdot 7 \)
Generators: $a, b^{6}, b^{4}, b, c^{5}$ Copy content Toggle raw display
Derived length: $2$

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

Ambient group ($G$) information

Description: $C_{35}:Q_{16}$
Order: \(560\)\(\medspace = 2^{4} \cdot 5 \cdot 7 \)
Exponent: \(280\)\(\medspace = 2^{3} \cdot 5 \cdot 7 \)
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_{70}.(C_2^4\times C_{12})$
$\operatorname{Aut}(H)$ $C_2\times D_4\times F_7$, of order \(672\)\(\medspace = 2^{5} \cdot 3 \cdot 7 \)
$\operatorname{res}(S)$$C_2\times D_4\times F_7$, of order \(672\)\(\medspace = 2^{5} \cdot 3 \cdot 7 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(4\)\(\medspace = 2^{2} \)
$W$$C_7:D_4$, of order \(56\)\(\medspace = 2^{3} \cdot 7 \)
