http://r-survey.r-forge.r-project.org/survey/html/paley.html Web3.2 The Paley Construction In 1933, Raymond Paley introduced a new family of Hadamard matrices and proved their existence ([11],[1]). He also provided methods for constructing these matrices. Paley’s constructions have been generalized; Assmus and Key refer us to chapter 14 of Hall ([9]) for a treatment of these generalizations. homemade fat free ranch dressing
