| Abstract： |
The necessary and sufficient conditions for the existence of simple incomplete block design (v,w; 4, 2)-IPBDs are determined. As a consequence, the necessary and sufficient conditions for the embeddings of simple two-fold balanced incomplete block designs with block size 4 are also determined. |
