set

Also known as mathematical set, sets (mathematics)

well-defined mathematical collection of distinct objects

AI overview

A set is a well-defined mathematical collection of distinct objects, where each object either belongs to the set or doesn't. Sets matter because they form the foundation for modern mathematics, allowing mathematicians to precisely define and work with groups of objects in logic, algebra, and many other fields.
