SOME CONSTRUCTIONS OF BALANCED INCOMPLETE BLOCK DESIGN WITH NESTED ROWS AND COLUMNS

Many researchers have given methods of construction of balanced incomplete blockdesigns with nested rows and columns. In this paper some new methods of construction ofbalanced incomplete block designs with nested rows and columns are developed. The paperconcludes with a numerical illustration and the appendix consists of parameters of some BIB-RCdesigns with their efficiencies and efficiency factors.
