G-designs of complete multipartite graph with G has five points-four edges or five points-five edges is studied.

讨论了完全多部图G设在性，其中G是五点四边图五点五边图。

A semicomplete multipartite digraph is obtained by replacing each edge of a complete multipartite graph by an arc or by a pair of two mutually opposite arcs.

摘要 用条对方向相反代替完全多部无向图每条边所得到有向图被称为是半完全多部有向图。
