Math::Combinatorics  Perform combinations and permutations on lists
Combinatorics is the branch of mathematics studying the enumeration, combination, and permutation of sets of elements and the mathematical relations that characterize their properties. As a jumping off point, refer to: http://mathworld.wolfram.com/Co...

Math::Counting  Combinatorial counting operations
Compute the factorial, number of permutations, number of derangements and number of combinations. The ":big" functions are wrappers around "bfac" in Math::BigInt with a bit of arithmetic between. The student versions exist to illustrate the computati...

Math::DyckWords  Perl module for generating Dyck words. Dyck words are named after the mathematician Walther von Dyck.
Dyck words are even numbered string of X's and Y's, or 0's and 1's, or any other binary alphabet for that matter, such that no initial segment has more Y's or 1's. The following are the Dyck words of length 2n where n = 3: 000111 010011 010101 001101...

Math::DifferenceSet::Planar  object class for planar difference sets
A planar difference set in a modular integer ring ℤ_n, or cyclic planar difference set, is a subset D = {d_1, d_2, ..., d_k} of ℤ_n such that each nonzero element of ℤ_n can be represented as a difference (d_i  d_j) in exactly one way. By convention...

Math::PlanePath::HilbertCurve  2x2 selfsimilar quadrant traversal
This path is an integer version of the curve described by Hilbert in 1891 for filling a unit square. It traverses a quadrant of the plane one step at a time in a selfsimilar 2x2 pattern, David Hilbert, "Ueber die stetige Abbildung einer Linie auf ei...
