Fast Generators and Iterators for Permutations, Combinations, Integer Partitions and Compositions R package arrangements version 1.1.10 CRAN Task View: NumericalMathematics (https://CRAN.R-project.org/view=NumericalMathematics) Fast generators and iterators for permutations, combinations, integer partitions and compositions. The arrangements are in lexicographical order and generated iteratively in a memory efficient manner. It has been demonstrated that 'arrangements' outperforms most existing packages of similar kind.
