Hey
How could I get all combination of the given list where each item in the list is a tuple and the combination should be made based on the second element. The second element is a list containing minium one and maximum four atoms.

Input:

[
    {{1, 1}, [:w, :e]},
    {{1, 3}, [:e]},
    {{2, 3}, [:n, :s]}
]

Output:

[
      [
        {{1, 1}, [:w]},
        {{1, 3}, [:e]},
        {{2, 3}, [:n]}
      ],
      [
        {{1, 1}, [:w]},
        {{1, 3}, [:e]},
        {{2, 3}, [:s]}
      ],
      [
        {{1, 1}, [:e]},
        {{1, 3}, [:e]},
        {{2, 3}, [:n]}
      ],
      [
        {{1, 1}, [:e]},
        {{1, 3}, [:e]},
        {{2, 3}, [:s]}
      ]
    ]
