Ranks and unranks permutations
This JavaScript library ranks and unranks permutations using an algorithm based on a 2000 paper by Myrvold and Ruskey. It is designed for developers who need to efficiently map between permutations and their corresponding integer ranks, such as those working on combinatorial algorithms or data structures.
