Subgroup ($H$) information

Description:$C_{33}$
Order: \(33\)\(\medspace = 3 \cdot 11 \)
Index: \(4\)\(\medspace = 2^{2} \)
Exponent: \(33\)\(\medspace = 3 \cdot 11 \)
Generators: $b^{22}, b^{3}$ Copy content Toggle raw display
Nilpotency class: $1$
Derived length: $1$

The subgroup is characteristic (hence normal), a semidirect factor, cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary ($p = 3,11$), hyperelementary, metacyclic, metabelian, a Z-group, and an A-group), and a Hall subgroup.

Ambient group ($G$) information

Description: $C_3:C_{44}$
Order: \(132\)\(\medspace = 2^{2} \cdot 3 \cdot 11 \)
Exponent: \(132\)\(\medspace = 2^{2} \cdot 3 \cdot 11 \)
Derived length:$2$

The ambient group is nonabelian, a Z-group (hence solvable, supersolvable, monomial, metacyclic, metabelian, and an A-group), and hyperelementary for $p = 2$.

Quotient group ($Q$) structure

Description: $C_4$
Order: \(4\)\(\medspace = 2^{2} \)
Exponent: \(4\)\(\medspace = 2^{2} \)
Automorphism Group: $C_2$, of order \(2\)
Outer Automorphisms: $C_2$, of order \(2\)
Nilpotency class: $1$
Derived length: $1$

The quotient is cyclic (hence abelian, nilpotent, solvable, supersolvable, monomial, elementary, hyperelementary, metacyclic, metabelian, a Z-group, and an A-group) and a $p$-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_{10}\times D_6$, of order \(120\)\(\medspace = 2^{3} \cdot 3 \cdot 5 \)
$\operatorname{Aut}(H)$ $C_2\times C_{10}$, of order \(20\)\(\medspace = 2^{2} \cdot 5 \)
$\operatorname{res}(\operatorname{Aut}(G))$$C_2\times C_{10}$, of order \(20\)\(\medspace = 2^{2} \cdot 5 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(6\)\(\medspace = 2 \cdot 3 \)
$W$$C_2$, of order \(2\)
