"""Fast Generators and Iterators for Permutations, Combinations, Integer
Partitions and Compositions.
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. Benchmarks could be found at
<https://randy3k.github.io/arrangements/articles/benchmark.html>."""
