k-tuple | tuple

An n-tuple, sometimes simply called a "tuple" when the number n is known implicitly, is another word for a list, i.e., an ordered set of n elements. It can be interpreted as a vector, or more specifically, an n-vector. In the Wolfram Language, n-tuples of length n in the alphabet consisting of the members in a list l can be enumerated using Tuples[list, n]. The following table summarizes special names given to n-tuples for small n.
