Large set (combinatorics)

In combinatorics, a "large set" typically refers to a set whose size (or cardinality) is significantly large in comparison to some other relevant quantity or in the context of the problem being studied. The notion of "large" can be context-dependent and may relate to different concepts in various combinatorial settings, such as the size of the set in relation to its properties, the size of a family of sets, or the number of elements fulfilling certain conditions.
