Subgroup ($H$) information
Description: | $C_{107}$ |
Order: | \(107\) |
Index: | \(12\)\(\medspace = 2^{2} \cdot 3 \) |
Exponent: | \(107\) |
Generators: |
$b^{6}$
|
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 $107$-Sylow subgroup (hence a Hall subgroup), a $p$-group, and simple.
Ambient group ($G$) information
Description: | $C_2\times C_{642}$ |
Order: | \(1284\)\(\medspace = 2^{2} \cdot 3 \cdot 107 \) |
Exponent: | \(642\)\(\medspace = 2 \cdot 3 \cdot 107 \) |
Nilpotency class: | $1$ |
Derived length: | $1$ |
The ambient group is abelian (hence nilpotent, solvable, supersolvable, monomial, metabelian, and an A-group), elementary for $p = 2$ (hence hyperelementary), and metacyclic.
Quotient group ($Q$) structure
Description: | $C_2\times C_6$ |
Order: | \(12\)\(\medspace = 2^{2} \cdot 3 \) |
Exponent: | \(6\)\(\medspace = 2 \cdot 3 \) |
Automorphism Group: | $D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \) |
Outer Automorphisms: | $D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \) |
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
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 $W = G / Z_G(H)$.
$\operatorname{Aut}(G)$ | $D_6\times C_{106}$, of order \(1272\)\(\medspace = 2^{3} \cdot 3 \cdot 53 \) |
$\operatorname{Aut}(H)$ | $C_{106}$, of order \(106\)\(\medspace = 2 \cdot 53 \) |
$\operatorname{res}(\operatorname{Aut}(G))$ | $C_{106}$, of order \(106\)\(\medspace = 2 \cdot 53 \) |
$\card{\operatorname{ker}(\operatorname{res})}$ | \(12\)\(\medspace = 2^{2} \cdot 3 \) |
$W$ | $C_1$, of order $1$ |
