Subgroup ($H$) information

Description:$D_{70}:C_{10}$
Order: \(1400\)\(\medspace = 2^{3} \cdot 5^{2} \cdot 7 \)
Index: \(28\)\(\medspace = 2^{2} \cdot 7 \)
Exponent: \(140\)\(\medspace = 2^{2} \cdot 5 \cdot 7 \)
Generators: $\left(\begin{array}{rr} 163 & 0 \\ 0 & 50 \end{array}\right), \left(\begin{array}{rr} 59 & 0 \\ 0 & 181 \end{array}\right), \left(\begin{array}{rr} 81 & 0 \\ 0 & 170 \end{array}\right), \left(\begin{array}{rr} 1 & 0 \\ 0 & 153 \end{array}\right), \left(\begin{array}{rr} 1 & 0 \\ 0 & 49 \end{array}\right), \left(\begin{array}{rr} 0 & 1 \\ 1 & 0 \end{array}\right)$ Copy content Toggle raw display
Derived length: $2$

The subgroup is nonabelian, supersolvable (hence solvable and monomial), and metabelian.

Ambient group ($G$) information

Description: $C_{140}\wr C_2$
Order: \(39200\)\(\medspace = 2^{5} \cdot 5^{2} \cdot 7^{2} \)
Exponent: \(280\)\(\medspace = 2^{3} \cdot 5 \cdot 7 \)
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 $W = N_G(H) / Z_G(H)$.
