Are you refering to a concrete algorithm?

To generate all permutations, you could use different algorithms.

One could be:
Generate a collection of combined objects, where every possible element is used as head, and the remaining elements are a Collection of remaining elements.

Repeat this method for the remaining elements, until they are all consumed.

Can you describe what you've tried? And why you think it's not working?
