Combinatorics is the study of discrete structures in general and enumeration on discrete structures in particular. For example, the number of three-cycles in a given graph is a combinatoric problem, as is the derivation of an analytic solution to the Fibonacci recurrence, and so too methods of solving the Rubiks cube. Different kinds of counting problems can be approached by a variety of techniques, such as generating functions or the inclusion-exclusion principle.
