Abstract
The path numbers of the mth order, (m)Z, of a connected undirected gra ph are introduced and studied analitically. The definition of the (1)Z and (2)Z indices for acyclic graphs proposed earlier is generalized i n order to cover cyclic graphs. The relationships between the path num bers (1)Z and (2)Z and the Hosoya Z index are discussed. It is shown t hat the path number (1)Z and the Hosoya Z index are closely related gr aph-theoretical invariants, The information contents of the (1)Z and ( 2)Z indices are only slightly overlapped, and hence the indices could be used as ''independent'' predictor variables in structure-property-a ctivity studies.
