Classification of Strongly Conflict-Avoiding Codes

Strongly conflict-avoiding codes (SCACs) for slot-asynchronous multiple-access collision channels without feedback are considered. Codes with maximum size (optimal codes) for given parameters are of interest. In this letter, we present classification results about optimal SCACs of weights 3, 4, and 5 and given small lengths. We also determine some previously unknown values of the size of optimal SCACs with these parameters.
