The numbers of the nearest neighbors, the next-nearest neighbors, the next-next-nearest neighbors, the 4-th and the 5-th neighbors are calculated. The functional dependence of the node-to-node distance d_{ij} on the product of connectivities k_ik_j has been also checked. The results of simulations for exponential networks agree with the existing analytical predictions.5 pages, RevTeX4, 3 figures with 9 eps files, dedicated to Professor Andrzej Z.
