In [2], on page 252 the following logical terminal inexactitude was made: “... the existence of a K 4 is the only obstruction. That is, every finite K 4 ‐free graph can be represented by odd‐distances in the plane .” In this note we correct this erroneous claim by showing that W 5 , the 5‐wheel, see Figure 1, is not a subgraph of G o d d .
