The sparsity of orthogonal matrices which have k 1 columns of nonzeros is studied. It is shown that the minimum number of nonzero entries in such an m by m matrix is As a consequence it is shown that if A is an m by n matrix with m < n and the properties that its rows are pairwise orthogonal, and i
