Definition:Ordered Tuple/Also known as

Definition

Some sources refer to an ordered tuple as a tuple.

The term ordered $n$-tuple or just $n$-tuple can sometimes be seen, particularly for specific instances of $n$.

Instead of writing $2$-tuple, $3$-tuple and $4$-tuple, the terms couple, triple and quadruple are usually used.

However, beware of couple, as this has a completely different meaning in the context of mechanics.

In the context of abstract algebra, the concept is encountered as (associative) word.

It is noted that an ordered tuple is in fact a one-dimensional array.
