New results on maximal sign-nonsingular (SNS) matrices are derived, among which new methods for constructing new SNS matrices from smaller SNS matrices. The results are used to produce a matrix definition for the \(C_4\) cockades and to introduce new families of SNS matrices not previously defined. All the results are deduced with the help of tables of maximal, irreducible SNS matrices of orders 3 to 9.
