The Wiener number of a molecular graph, or more generally of a connected graph, is equal to the sum of distances between all pairs of its vertices. A graph formed by a hexagon in the centre, surrounded by n rings of hexagonal cells, is called an n-hexagonal net. It is shown that the Wiener number of

The enumeration problem of Latin rectangles is formulated in terms of permanents, and two 'hard' inequalities of permanents are applied in a squeezing manner, both giving and suggesting asymptotic formulas.

An explicit analytical expression for E( W(n) ), the expected value of the Wiener number of a random benzenoid chain with n hexagons is obtained. In the general case, E( W(n) ) is not a polynomial in the variable n.
