Subgroup ($H$) information

Description:$C_2$
Order: \(2\)
Index: \(160\)\(\medspace = 2^{5} \cdot 5 \)
Exponent: \(2\)
Generators: $ab^{2}c^{3}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), a $p$-group, simple, and rational.

Ambient group ($G$) information

Description: $C_2^3.D_{20}$
Order: \(320\)\(\medspace = 2^{6} \cdot 5 \)
Exponent: \(20\)\(\medspace = 2^{2} \cdot 5 \)
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 $W = N_G(H) / Z_G(H)$.
