Get permutations of array numbers

Question

Hello,

Here below is a list molex_stubs of int arrays.

How to create a list of all permutation of array members where:

• list items are arrays of int
• item length is 14 (number of items in molex_stubs list
• 0-items of int arrays come from molex_stubs[0], 1st-item of int arrays come from molex_stubs[1], etc.

Thanks

List<int[]> molex_stubs = new List<int[]>()
{
    new int[] { 3, 1, -1, -3 },
    new int[] { 3, 1, -1, -2 },
    new int[] { 0 },
    new int[] { 4, 3, 1, -1, -3, -4 },
    new int[] { 2, 1, -1, -3 },
    new int[] { 0, -3 },
    new int[] { 3, 0 },

    new int[] { 3, 1, -1, -3 },
    new int[] { 4, 3, 1, -1, -3, -4 },
    new int[] { 3, 0 },
    new int[] { 2, 1, -1, -3 },
    new int[] { 0 },
    new int[] { 0, -3 },
    new int[] { 3, 1, -1, -2 }
};
