Example
Let G be the group S3. Then G consists of six elements:
e, y = (1,2,3), z = (1,3,2),
a = (1,2), b = (2,3), c = (1,3).
The three representations G -> Sym({a,b,c,e,y,z})
are written out explicitly.
L
R
C
Written as products of disjoint cycles,
the images of the five nontrivial elements under this permutation
representation are
- La = (a,e)(b,y)(c,z)
- Lb = (b,e)(a,z)(c,y)
- Lc = (c,e)(a,y)(b,z)
- Ly = (y,z,e)(a,c,b)
- Lz = (e,z,y)(a,b,c).
Note that the multiplication of
G can be easily recovered from the list.
For instance
Lc(
a) =
y
means
ca =
y.
Written as products of disjoint cycles,
the images of the five nontrivial elements under this permutation
representation are
- Ra = (a,e)(b,z)(c,y)
- Rb = (b,e)(a,y)(c,z)
- Rc = (c,e)(a,z)(b,y)
- Ry = (z,y,e)(a,b,c)
- Rz = (e,y,z)(a,c,b).
For instance,
Rc(
a) =
z
means
a =
zc.
Written as products of disjoint cycles,
the images of the five nontrivial elements under this permutation
representation are
- Ca = (b,c)(y,z)
- Cb = (a,c)(y,z)
- Cc = (a,b)(y,z)
- Cy = (a,b,c)
- Cz = (a,c,b).
For instance,
Cc(
a) =
b
means
ca =
bc.
