Explore Combinatorics on MathWorld

Combinatorica is the branch of mathematics studying the enumeration, combination, and permutation of sets of elements and the mathematical relations that characterize these properties.

Combinatorics is a college-level concept that would be first encountered in a discrete mathematics course covering combinatorics.
