Construction of a repetitive magic square with Ramanujan's number as its product

Heliyon, 2023
In this article, we build a repetitive magic square by multiplying four elements. This square is a matrix with its corresponding elements. The elements of this matrix that take different values allow us to obtain Ramanujan's number 1729 as its ...

A Novel Latin Square Image Cipher

, 2012
In this paper, we introduce a symmetric-key Latin square image cipher (LSIC) for grayscale and color images. Our contributions to the image encryption community include 1) we develop new Latin square image encryption primitives including Latin Square ...

Completing simple partial k-Latin squares

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2018
We study the completion problem for simple k-Latin rectangles, which are a special case of the generalized latin rectangles studied for which embedding theorems are given by Andersen and Hilton (1980) in “Generalized Latin rectangles II: Embedding ...

Crisscross Latin squares

Journal of Combinatorial Theory, Series A, 1979
AbstractLet A be a Latin square of order n. Then the jth right diagonal of A is the set of n cells of A: {(i,j+i):i=0,1…,n−1(mod n); and the jth left diagonal of A is the set {(i,j−i):i=0,1…,n−1(mod n); A diagonal is said to be complete if every element appears in it exactly once.
