✦ Synopsis


In this paper, we consider total clique covers and intersection numbers on multifamilies. We determine the antichain intersection numbers of graphs in terms of total clique covers. From this result and some properties of intersection graphs on multifamilies, we determine the antichain intersection numbers of 3-, 4-, j-regular graphs and some special graphs.

Let G be a line graph. Orlin determined the clique covering and clique partition numbers cc(G) and cp(G). We obtain a constructive proof of Orlin's result and in doing so we are able to completely enumerate the number of distinct minimal clique covers and partitions of G, in terms of easily calculab
