Construction of variety competition cyclic balanced designs on square lattice
A class of cyclic balanced designs with ten test-hills is introduced; these designs can be repeated cyclically any number of times up to the requirement of the experimenter and subject to the availability of experimental material. The designs are balanced with respect to first order nearest neighbours and there are 26 isomorphism classes of such designs. The designs are suitable for de Wit repl...
متن کاملEquivalence classes of matchings and lattice-square designs
We enumerate nonisomorphic lattice-square designs yielded by a conventional construction. Constructed designs are speci3ed by words composed from 3nite-3eld elements. These words are permuted by the isomorphism group in question. The latter group contains a direct-product subgroup, acting, respectively, upon the positions and identities of the 3nite-3eld elements. We review enumeration theory f...
متن کاملConstruction and analysis of orthogonal (Graeco) Sudoku square designs
The present paper deals with the introduction of new experimental designs namely “Orthogonal Sudoku Square Designs”. A simple “sequential method” of constructing orthogonal Sudoku square designs (OSSD) of odd order is presented. The analysis of orthogonal Sudoku square designs is also discussed. The entire above is explained with the help of numerical examples.
متن کاملRank 3 Latin square designs
A Latin square design whose automorphism group is transitive of rank at most 3 on points must come from the multiplication table of an elementary abelian p-group,

We show that the operations of permuting columns and rows separately and independently mix a square matrix in constant time.
