| Abstract: | In the report, the gracefulness of the unconnected graph D2,6 U G was discussed. One sufficient con- dition was proposed for the gracefulness of unconnected graph D2,6 U G. It was proved that if G is balanced bipar- tite graph with certain conditions, the unconnected graph D2.6 U G is graceful graph. |

| Keywords: | graceful graph balanced bipartite graph unconnected graph graceful labeling |
