A set of polygons in an Euler diagram

In mathematics, a set is a well-defined collection of distinct objects, considered as an object in its own right.[1][2] The arrangement of the objects in the set does not matter. For example, the numbers 2, 4, and 6 are distinct objects when considered separately, but when they are considered collectively they form a single set of size three, written as {2, 4, 6}, which could also be written as {2, 6, 4}.[3]

The concept of a set is one of the most fundamental in mathematics.[4] Developed at the end of the 19th century,[5] set theory is now a ubiquitous part of mathematics, and can be used as a foundation from which nearly all of mathematics can be derived.
