AbstractThis paper explicitly constructs non-singular 0-1 matrices of dimensions n with constant row and column sum k, subject only to the conditions 0<k<n and (k,n)≠(2,4). An application of such matrices to finite geometries can be found in [1]
We present additional equivalent conditions on the existence of a 0 1 symmetric matrix with given ro...
