Rewrite, to correct the errors. At a convention, 128 people all need to meet with each other, 1 on 1, for a paper exchange. Suppose a room is divided into a 8x8 square, and a clock is set up to ding 127 times, once every 30 seconds. Each person is given a map of their starting square, and a map of their route over the next hour and 4 minutes. Only two people can be in each cell. Ideally, most moves should be King moves. Not needing to move during a turn is acceptable. Simplicity is judged by the amount of text needed to explain the choreography, and the orderliness of the room. Alternately, the length of the maximum walk should be minimised. Ed Pegg Jr
