Create a permutation by specifying the result of permuting [| 0 .. n-1 |]. For example,
|
|
Permutation.of_array [| 1;2;0 |] specifies a permutation that rotates all elements right one place.

Create a permutation by specifying (source,destination) index pairs. For example,
|
|
Permutation(3,[ (0,2);(1,0); (2,1) ]) specifies a permutation that rotates
|
|
all elements left one place. Not all elements need be given, e.g.
|
|
Permutation(5,[ (1,2);(2,1) |]) specifies a permutation that swaps elements at indexes
|
|
1 and 2.
