Constructing (0,1)matrices with large minimal defining sets
Cavenagh, Nicholas J.; Ramadurai, Reshma (Elsevier, 2018)If D is a partially filledin (0, 1)matrix with a unique completion to a (0, 1)matrix M (with prescribed row and column sums), we say that D is a defining set for M. Let A₂ₘ,ₘbe the set of (0, 1)matrices of dimensions ... 
On the distances between Latin squares and the smallest defining set size
Cavenagh, Nicholas J.; Ramadurai, Reshma (Elsevier, 2016)We show that for each Latin square L of order n ≥ 2 , there exists a Latin square L’ ≠ L of order n such that L and L’ differ in at most 8√n̅ cells. Equivalently, each Latin square of order n contains a Latin trade of ... 
On the Distances between Latin Squares and the Smallest Defining Set Size
Cavenagh, Nicholas J.; Ramadurai, Reshma (Wiley, 2017)In this note, we show that for each Latin square L of order n≥2 , there exists a Latin square L’≠L of order n such that L and L’ differ in at most 8√n cells. Equivalently, each Latin square of order n contains a Latin ...
