This paper proves that for every rational number
r between 3 and 4, there is a planar graph G whose
circular chromatic number is equal to r. Combining this
result with a recent result of Moser, we obtain the conclusion
that every rational number r between 2 and 4 is the circular
chromatic number of a planar graph.
