Maximum Sequence Lengths for Perfect Stranger Matching

Green cells indicate that this is a known optimal number of rounds. Orange cells indicate that a predefined set of groupings is used as published by Both et al. (2016)1. Blue cells indicate a construction approach which yields a number of rounds greater than or equal to that given by Both et al. (2016). Clicking cells redirects to the documentation for the method used to achieve each result.
