| Abstract: | Based on our previous paper, further property of gracefulness of digraph n·C 3 is obtained: each common vertex of two non-intersecting digraph n·C 3 connects with a new additional vertex through directional arcs. As a results, such a connection makes this digraph becomes a graceful graph when outdegree aguals to 2 or indegree aquals to 2. |
