We'll be back next Monday with another snippet post, this time covering a very interesting type of collection. Avoid some common pitfalls and ace your interview. In mathematics, the notion of permutation relates to the act of arranging all the members of a set into some sequence or order, or if the set is already ordered, rearranging (reordering) its elements, a process called permuting. It's possible to include instances where an item is paired with itself using the combinations_with_replacement function. Reply. At least I thought it would be simple when I was pseudocoding it. Providing an r value greater than the length of the collection passed into permutations will yield an empty permutations object. The number of permutations on the set of n elements is given by n!
