Classification Of Small Strength-2 Covering Arrays

The files contain strength-2 covering arrays classified in the study "J. I. Kokkala, K. Meagher, R. Naserasr, K. J. Nurmela, P. R. J. Östergård, B. Stevens, On the Structure of Small Strength-2 Covering Arrays". Each line in a file corresponds to a \(\mathrm{CA}(N;2,k,v)\), rows of the covering array are separated by space. The file name format is <em>ca_N_2_k_v.txt</em> if all covering arrays were classified. Whenever only uniform covering arrays are classified, the file name is <em>uca_N_2_k_v.txt</em>. An additional suffix <em>_delta_δ</em> in the file name implies that only covering arrays with that \(\delta\) parameter (see the publication) were classified. In some cases, the number of inequivalent covering arrays was too large for the arrays to be stored; those cases are omitted here.
