A set is a collection of unique items; this word has a very specific meaning, implying that there is no particular order to the items (so two boxes of assorted chocolates, regardless of their place in the box, etc.). How can I succinctly refer to a set which does impose an order on the items, which is not implied by any property of those items (for example, alphabetical sorting), where two such collections are the same only if they appear in the same order? Another way of thinking about it is that it is a numbered sequence/list of entries, where no entry is repeated.
It can be a noun, an adjective, past participle or even a very short phrase (or rather, two to three words). I don't think there is a proper word for it, but I specifically do not want to mention a set as it would be misleading; similarly, 'sorted' seems to imply that it happens based on some clue/property of the items, rather than being an arbitrary order.
