Two weighing matrices are considered to be equivalent if one can be obtained from the other by a series of permutations and negations of the rows and columns of the matrix. The classification of weighing matrices is complete for cases where ≤ 5 as well as all cases where ≤ 15 are also completed. However, very little has been done beyond this with exception to classifying circulant weighing matrices.
