Permutations vs. Combinations

Question

What are the word modifiers in order to distinguish a given if it is a permutation or a combination? Or simply describe what is permutation and combination.

Answer 1

The only difference between them is that in a permutation the order of the elements matters while in a combination doesn't.

Answer 2

"Permutation" vs. "Combination" is not about "choosing" or "not choosing". It's about whether the order matters or not.

If order does not matter, it is a combinations problem. If order does matter, it is a permutations problem.

And there is also a difference between how you count and what you are counting.
