In mathematics and computer science a tuple captures the intuitive notion of an ordered list of elements. Depending on the mathematical foundation chosen, the formal notion differs slightly. In set theory, an (ordered) n-tuple is a sequence (or ordered list) of n elements, where n is a positive integer. The main properties that distinguish a tuple from, for example, a set are that 1. It can contain an object more than once; 2. The objects appear in a certain order; 3. It has finite size.
