Subgroup ($H$) information

Description:$C_{44}$
Order: \(44\)\(\medspace = 2^{2} \cdot 11 \)
Index: \(10\)\(\medspace = 2 \cdot 5 \)
Exponent: \(44\)\(\medspace = 2^{2} \cdot 11 \)
Generators: $b^{11}, b^{22}, b^{4}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is normal and cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,11$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group).

Ambient group ($G$) information

Description: $C_{44}.C_{10}$
Order: \(440\)\(\medspace = 2^{3} \cdot 5 \cdot 11 \)
Exponent: \(220\)\(\medspace = 2^{2} \cdot 5 \cdot 11 \)
Derived length:$2$

The ambient group is nonabelian and metacyclic (hence solvable, supersolvable, monomial, and metabelian).

Quotient group ($Q$) structure

Description: $C_{10}$
Order: \(10\)\(\medspace = 2 \cdot 5 \)
Exponent: \(10\)\(\medspace = 2 \cdot 5 \)
Automorphism Group: $C_4$, of order \(4\)\(\medspace = 2^{2} \)
Outer Automorphisms: $C_4$, of order \(4\)\(\medspace = 2^{2} \)
Nilpotency class: $1$
Derived length: $1$

The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 2,5$), hyperelementary, metacyclic, metabelian, a Z-group, 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 $W = N_G(H) / Z_G(H)$.

$\operatorname{Aut}(G)$$S_4\times F_{11}$, of order \(2640\)\(\medspace = 2^{4} \cdot 3 \cdot 5 \cdot 11 \)
$\operatorname{Aut}(H)$ $C_2\times C_{10}$, of order \(20\)\(\medspace = 2^{2} \cdot 5 \)
$\operatorname{res}(S)$$C_2\times C_{10}$, of order \(20\)\(\medspace = 2^{2} \cdot 5 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(44\)\(\medspace = 2^{2} \cdot 11 \)
$W$$C_{10}$, of order \(10\)\(\medspace = 2 \cdot 5 \)
