Homework Assignment
Network Puzzle

In the Bavelas-Leavitt experiments, the circle configuration (see figure below) did not perform very well. This is surprising because theoretically it can transmit information to all parties much faster than all the other configurations. In fact, it can solve the puzzle in 3 units of time, whereas the star (aka wheel) requires a minimum of 5 units of time.

Your task is to show how the circle can solve the puzzle in 3 units of time. Recall the rules:

Your job is to figure out what is the minimum number of units of time required so that every person has everyone else's unique information.
