A permutation which shifts all elements of a set by a fixed offset, with the elements shifted off the end inserted back at the beginning.
For a set with elements 
, 
, ..., 
, a cyclic permutation of one place to the left would
yield 
,
..., 
,
,
and a cyclic permutation of one place to the right would yield 
, 
, 
, ....
The mapping can be written as 
for a shift of 
places. A shift of 
places to the left is implemented in the Wolfram
Language as RotateLeft[list,
k], while a shift of 
places to the right is implemented as RotateRight[list,
k].
