Subgroup ($H$) information

Description:$C_{11}\times C_{110}$
Order: \(1210\)\(\medspace = 2 \cdot 5 \cdot 11^{2} \)
Index: \(20\)\(\medspace = 2^{2} \cdot 5 \)
Exponent: \(110\)\(\medspace = 2 \cdot 5 \cdot 11 \)
Generators: $c^{55}, b^{2}, c^{10}, c^{22}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is normal, a semidirect factor, abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), elementary for $p = 11$ (hence hyperelementary), and metacyclic.

Ambient group ($G$) information

Description: $C_2\times C_{110}:F_{11}$
Order: \(24200\)\(\medspace = 2^{3} \cdot 5^{2} \cdot 11^{2} \)
Exponent: \(110\)\(\medspace = 2 \cdot 5 \cdot 11 \)
Derived length:$2$

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

Quotient group ($Q$) structure

Description: $C_2\times C_{10}$
Order: \(20\)\(\medspace = 2^{2} \cdot 5 \)
Exponent: \(10\)\(\medspace = 2 \cdot 5 \)
Automorphism Group: $C_4\times S_3$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
Outer Automorphisms: $C_4\times S_3$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
Nilpotency class: $1$
Derived length: $1$

The quotient is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), elementary for $p = 2$ (hence hyperelementary), and metacyclic.

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

$\operatorname{Aut}(G)$$C_{22}^2.C_5.C_{30}.C_{10}.C_2^4$
$\operatorname{Aut}(H)$ $C_4\times C_{10}.\PSL(2,11).C_2$
$W$$C_{10}$, of order \(10\)\(\medspace = 2 \cdot 5 \)
