Some New Maximal Sets of Mutually Orthogonal Latin Squares

Designs, Codes and Cryptography, 2003
A set of \(t\) mutually orthogonal Latin squares is maximal if it cannot be embedded in a larger set. The problem of constructing such maximal sets can be formulated in a geometric language and is then part of Galois geometries. In the present paper a computer classification of maximal partial spreads of \(\text{PG}(3,4)\setminus \text{PG}(3,2)\) is ...

Sets of Mutually Orthogonal Sudoku Latin Squares

The College Mathematics Journal, 2009
Ryan Pedersen (Ryan.Pedersen@ucdenver.edu) received his B.S. in mathematics and his B.A. in physics from the University of the Pacific, and his M.S. in applied mathematics from the University of Colorado Denver, where he is currently finishing his Ph.D. His research is in the field of finite projective geometry.

On Maximal Sets of Mutually Orthogonal Idempotent Latin Squares

Canadian Mathematical Bulletin, 1971
It is a well-known trivial fact that for a given integer n there exists at most n — 2 pairwise orthogonal idempotent latin squares. In the following note we prove that for n a prime power there always exists n—2 such squares.

On the number of mutually orthogonal partial latin squares

Ars Comb., 1996
A partial latin square of order \(n\) is an \(n\times n\) array such that each of the integers \(1,2,\dots,n\) appears at most once in any row or column. Two partial latin squares are orthogonal if all ordered pairs of entries obtained by superimposing the two squares are distinct and a collection of partial latin squares is orthogonal if each pair of ...

Construction Techniques for Mutually Orthogonal Latin Squares

1995
Recent developments concerning the construction of mutually orthogonal latin squares (MOLS) and incomplete MOLS are discussed. Some improvements in the number of MOLS are presented using Greig’s line-flip technique, and some new sets of incomplete MOLS found by computer search are presented. Finally, a variant of Wilson’s theorem is developed.
