Title: Subset Authors: Venue: Wikipedia Year: unknown Canonical: wiki:subset URL: https://en.wikipedia.org/wiki/Subset Collector: wikipedia OA: true ABSTRACT In mathematics, a set A is a subset of a set B if and only if all elements of A are also elements of B; B is then a superset of A. It is possible for A and B to be equal; if they are unequal, then A is a proper subset of B. The relationship of one set being a subset of another is called inclusion. A is a subset of B may also be expressed as B includes A or A is included in B. A k-subset is a subset with k elements.
