Subgroup ($H$) information

Description:$C_2$
Order: \(2\)
Index: \(385\)\(\medspace = 5 \cdot 7 \cdot 11 \)
Exponent: \(2\)
Generators: $a$ 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 $2$-Sylow subgroup (hence a Hall subgroup), a $p$-group, simple, and rational.

Ambient group ($G$) information

Description: $C_{11}\times D_{35}$
Order: \(770\)\(\medspace = 2 \cdot 5 \cdot 7 \cdot 11 \)
Exponent: \(770\)\(\medspace = 2 \cdot 5 \cdot 7 \cdot 11 \)
Derived length:$2$

The ambient group is nonabelian, a Z-group (hence solvable, supersolvable, monomial, metacyclic, metabelian, and an A-group), and hyperelementary for $p = 2$.

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 $W = N_G(H) / Z_G(H)$.
