Subgroup ($H$) information

Description:$C_{11}:C_{20}$
Order: \(220\)\(\medspace = 2^{2} \cdot 5 \cdot 11 \)
Index: \(24\)\(\medspace = 2^{3} \cdot 3 \)
Exponent: \(220\)\(\medspace = 2^{2} \cdot 5 \cdot 11 \)
Generators: $b^{15}cd^{22}, d^{22}, d^{4}, b^{6}$ Copy content Toggle raw display
Derived length: $2$

The subgroup is nonabelian and a Z-group (hence solvable, supersolvable, monomial, metacyclic, metabelian, and an A-group).

Ambient group ($G$) information

Description: $F_{11}\times \GL(2,3)$
Order: \(5280\)\(\medspace = 2^{5} \cdot 3 \cdot 5 \cdot 11 \)
Exponent: \(1320\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \cdot 11 \)
Derived length:$4$

The ambient group is nonabelian and solvable.

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