Some new disjoint Golomb rulers

Let a Golomb ruler be a set {a_i} of integers so that all the differences a_i-a_j, i≠j, are distinct. Let H(I.J) be the smallest n such that there are I disjoint Golomb rulers each containing J elements chosen from {1,2,...n}. In 1990, Klove gave a table of bounds on H(I,J). In this correspondence we improve and extend this table with results found by computer search
