A Note on the Sequential Sign Test

players with five rounds similar to the five round layout given in the discussion but with the added feature that if two are partners they will not share any other partners. For example, if one and two play together, as they do in round one, then the sets of remaining partners for one and two do not contain any of the same individuals. However, this was never successfully accomplished. In the design that is presented, the pairs in round five, such as 1-5, have the same four as partners in the other four rounds. For 1 and 5 these partners are 2, 6, 10, and 14. The pairs in other rounds share just two other partners. 1 and 2, partners in round 1, share partnership with 5 and 6.
