Questions on the use of Mathematica in combinatorics, including the Combinatorica add-on package. Combinatorics is the branch of mathematics studying the enumeration, combination, and permutation of sets of elements and the mathematical relations that characterize their properties. This involves built in functions sucha as Tuples, Permutations, Signature, Ordering, Cycles, etc.

More general questions on sets, lists or sequences of elements might want to use the tag . Questions about order of elements in a list and about sorting lists should use the tag . Questions about permutations should use .
