Some Orthogonal Designs Constructed From Circulant Weighing Matrices
- …Circulant weighing matrices are used to construct some new innite families of short amicable sets and amicable sets. These give new innite families of orthogonal designs in four and eight variables. Among others OD(56; 3; 3; 3; 3; 3; 3; 12; 12) and OD(168; 1; 1; 3; 3; 6; 6; 8; 8) are constructed her…

Infinite Families of Orthogonal Designs: I
- …We generalize a method inspired by Kharaghani and Holzmann to obtain infinite families of 6-variables orthogonal designs, OD(8t; k; k; k; k; k; k), and OD(8t; k; k; k; k; 2k; 2k), for the first time for odd t.…

A Search for Hadamard Matrices constructed from Williamson Matrices
- …We describe the implementation of a distributed computer search that uses Williamson's construction for Hadamard matrices. The search program is used to perform a complete search for matrices of orders 100 through 148. No new results are found, confirming existing results. We are convinced that no f…

New Weighing Matrices and Orthogonal Designs Constructed Using Two Sequences With Zero Autocorrelation Function - a Review
- …The book, Orthogonal Designs: Quadratic Forms and Hadamard Matrices, Marcel Dekker, New York-Basel, 1979, by A. V. Geramita and Jennifer Seberry, has now been out of print for almost two decades. Many of the results on weighing matrices presented therein have been greatly improved. Here we revie…
