Abstract: Constructions of so-called “strong orthogonal arrays” (SOAs) have been previously proposed. The approaches and notations taken in the different proposals vary widely. The SOAs and their constructions are reviewed using a unifying notation with a simple set of equations. In addition to providing a unifying overview, some constructions are improved, e.g., by enforcing column orthogonality via a bipartite pair matching algorithm where the original constructions pay no attention to column orthogonality. All presented constructions are implemented in the R package SOAs. As an aside, it is argued that “stratum” is a better choice than “strong” for the “S” in the acronym SOAs.
