In some cases, there may be more than one acronym corresponding to the same set of numbers. For example R and WR are used for Rausch's numbers, L and LAU for Lau's numbers, and so on. In such cases, all possibilities will be returned. No distinction is made here according to capitalisation, so e.g. KK, Kk and kk are all treated the same.
