Namespace:  Kaos.Combinatorics
Assembly:  KaosCombinatorics (in KaosCombinatorics.dll) Version: 6.0.0.0
Syntax
C#
Copy
public IEnumerable<Permutation> GetRows()

Return Value

Type: IEnumerablePermutation
An iterator for a Permutation table.
Remarks
If the start row is not Rank 0, the iteration will wrap around so that RowCount items are always produced.
Examples
C#
Copy
using System;
using Kaos.Combinatorics;

namespace ExampleApp
{
    class PnExample01
    {
        static void Main()
        {
            var pn = new Permutation (choices:4);

            Console.WriteLine ($"n={pn.Choices}:\n");

            foreach (var row in pn.GetRows())
                Console.WriteLine ($"{row.Rank,2}:  {row}");
        }
