When three villages are arranged in a triangular formation with specific distances, are they combined into one city for teḥum measurement?
Synopsis
Three villages in a triangular arrangement combine into one city if the middle village is within 1000 amot of each of the outer villages and the outer villages are within 283 amot minus one-third of each other (exclusive of the middle village's width). There is a dispute whether the middle village itself measures from the outer villages or only from its own walls.
