An n-tuple is an ordered list of n numbers: (a1, a2, ..., an). Pairs and triples are the 2- and 3-tuples; the n-tuple makes the idea general. Databases call every row a tuple, machine learning calls them feature vectors, and geometry calls them points in n-dimensional space - one word, many dimensions.
Generate Tuples of Numbers builds n-tuples of any arity from 2 to 12, with each component drawn from the range you set. Every row shows its sum and n-dimensional distance, and a no-repeat option keeps the set unique. Up to 1000 tuples, copy or download.
