Construction of symmetric Hadamard matrices of order for
N. A. Balonin, D. Z. Djokovic, D. A. Karbovskiy
We continue our systematic search for symmetric Hadamard matrices based on the so called propus construction. In a previous paper this search covered the orders with odd $v\le…
Construction of symmetric Hadamard matrices
N. A. Balonin, Y. N. Balonin, D. Z. Djokovic +2
We systematically explore the new method of construction (known as the propus construction) of symmetric Hadamard matrices for small orders, . In particular we give the first e…
The Propus Construction for Symmetric Hadamard Matrices
Jennifer Seberry, N. A. Balonin
\textit{Propus} (which means twins) is a construction method for orthogonal matrices based on a variation of the Williamson array called the \textit{propus array} \[ \begin…
Cretan(4t+1) Matrices
N. A. Balonin, Jennifer Seberry
A matrix, of order , is an orthogonal matrix whose elements have moduli . The only matrices previously published are for orders 5, 9, 13…
Two-level Cretan Matrices Constructed Theoretically and Computationally using SBIBD
N. A. Balonin, Jennifer Seberry
Cretan matrices are orthogonal matrices with elements . These may have application in forming some new materials. There is a search for Cretan matrices, especially with hig…
