Subgroup ($H$) information

Description:$C_{11}$
Order: \(11\)
Index: \(2420\)\(\medspace = 2^{2} \cdot 5 \cdot 11^{2} \)
Exponent: \(11\)
Generators: $a^{10}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

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

Ambient group ($G$) information

Description: $C_{11}\times C_{22}:F_{11}$
Order: \(26620\)\(\medspace = 2^{2} \cdot 5 \cdot 11^{3} \)
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: $C_{22}:F_{11}$
Order: \(2420\)\(\medspace = 2^{2} \cdot 5 \cdot 11^{2} \)
Exponent: \(110\)\(\medspace = 2 \cdot 5 \cdot 11 \)
Automorphism Group: $F_{11}^2:C_2^2$, of order \(48400\)\(\medspace = 2^{4} \cdot 5^{2} \cdot 11^{2} \)
Outer Automorphisms: $C_2^2\times C_{10}$, of order \(40\)\(\medspace = 2^{3} \cdot 5 \)
Nilpotency class: $-1$
Derived length: $2$

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

Automorphism information

Since the subgroup $H$ is characteristic, the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : \operatorname{Aut}(G) \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphism group $\operatorname{Inn}(G)$ is the Weyl group $W = G / Z_G(H)$.

$\operatorname{Aut}(G)$$C_{11}^2.C_5.C_{10}^2.C_2^3$
$\operatorname{Aut}(H)$ $C_{10}$, of order \(10\)\(\medspace = 2 \cdot 5 \)
$W$$C_1$, of order $1$
