Abstract

Orthogonal arrays are important combinatorial structures, both from a theoretical and a practical point of view. This fact is based on their close relation with other combinatorial structures and their practical application for testing and planning of experiments. For this reason, the orthogonal arrays are of a great research interest for many authors who explore different methods for construction, classification of orthogonal arrays, etc. In this paper we present a software package for investigation of orthogonal arrays. One of its functionalities is to check whether a matrix (or a set of matrices) satisfies the conditions for orthogonal array with fixed parameters. Another functionality of this package is the identification of isomorphic orthogonal arrays. Furthermore, OAtools provides the ability to calculate distance distribution.
