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

讨论了完图G设计存在性，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.
