finite set theory

Finite set theory studies collections of distinct objects that can be counted, meaning the number of elements is limited and known. It explores properties and operations on these sets, such as union, intersection, and difference, focusing on how finite groups relate and interact. This foundational area of mathematics helps define concepts in logic, computer science, and combinatorics, providing a rigorous framework for understanding how finite collections behave and how they can be manipulated or categorized systematically.
