 note = {We introduce the distance between two edges in a graph (nondirected graph) as the minimum number of edges in a tieset with the two edges. Using the distance between edges we define the eccentricity ετ (ej) of an edge ej. A finite nonempty set J of positive integers (no repetitions) is an eccentric set if there exists a graph G with edge set E such that ετ (ej) ∈ J for all ei　∈ E and each positive integer in J is ετ (ej) for some ej　∈ E. In this paper, we give necessary and sufficient conditions for a set J to be eccentric.},
