Constructing, Classifying and Studying the Space of Small Integer Weighing Matrices
Assaf Goldberger, Radel Ben-Av, Giora Dula +1
Integer weighing matrices (IW-matrices for short) are integer valued orthogonal square matrices. One usecase of these is to create classical weighing matrices with various block st…

The Classification of Circulant Weighing Matrices of Weight 16 and Odd Order
R. M. Adin, L. Epstein, Y. Strassler
In this paper we completely classify the circulant weighing matrices of weight 16 and odd order. It turns out that the order must be an odd multiple of either 21 or 31. Up to equiv…
