A code has two digits for the area, a letter for the second level and two digits for the third level, such as 81Q50 for quantum chaos. Codes that end in xx name a whole second-level class, such as 68Txx, and codes of the form 05-XX a whole area. The current edition is MSC2020. The regexp is the Wikidata format of property P3285; it does not accept a bare two-digit area.",
