Subgroup ($H$) information

Description:$C_{11}$
Order: \(11\)
Index: \(440\)\(\medspace = 2^{3} \cdot 5 \cdot 11 \)
Exponent: \(11\)
Generators: $c$ 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, and simple.

Ambient group ($G$) information

Description: $C_{11}^2:C_{40}$
Order: \(4840\)\(\medspace = 2^{3} \cdot 5 \cdot 11^{2} \)
Exponent: \(440\)\(\medspace = 2^{3} \cdot 5 \cdot 11 \)
Derived length:$2$

The ambient group is nonabelian, monomial (hence solvable), metabelian, and an A-group.

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