Statisticians are interested in designs for two non-interacting sets of treatments. These designs present many interesting combinatorial problems. The subject is reviewed from a combinatorial viewpoint, and unsolved problems are indicated. An extensive bibliography is appended.

Non-orthogonal graeco-latin designs

A list is given of combinatorial and statistical publications on (a) designs for comparative experiments in three space dimensions, and (b) other related designs.
