Any Hadamard matrix constructed by methods of R. E. A. C. Paley can be converted easily by one or two elementary matrix operations to a form sharing at least four desirable properties with standard forms of Walsh matrices: symmetry, zero trace, normal form, and the same number of 1's as -1's in every row and column except the 0th row and 0th column.
