Group construction of covering arrays

This project will look at a construction of strength 3 covering ar-rays developed by Chateauneuf, Colburn and Kreher. This construc-tion uses a subarray of a covering array and a group action on that subarray. 1 Introduction and Denitions Covering arrays are very interesting and useful designs that have been widely studied They are closely related to orthogonal arrays. They are also related to interesting mathematical structures, like set systems and intersecting codes. There are also many applications of coverin
