Two distinct Near-Resolvable BIBDs that are symmetric are equally obtained. All the aforementioned designs are constructed via orderly combinations of off-diagonal elements of a complete set of mutually orthogonal Latin squares (MOLS).enOrthogonal Latin Square, Symmetric, Near-Resolvable, Incomplete Block Designs, Partially Balanced Incomplete Block DesignsArticle
