Compound orthogonal arrays have recently been introduced as an alternative to Taguchi’s direct product arrays for studying location and dispersion effects simultaneously. In this article, we provide a catalog of two-level compound orthogonal arrays for parameters of most practical interest. The arrays presented possess the maximum possible strength for given numbers of factors and runs. Simple methods to obtain these arrays, using defining contrasts, are also presented.
