The mean isomer degeneracy of the Wiener index was previously shown to become unboundedly large as n (the number of vertices of the molecular graphs of the isomers considered) increases. We here show that there is a high isomer degeneracy in the case of molecules of medium size, namely when n = 6 and n = 7.
