Use the links above or do an advanced search in ppubs for:
(83/162.ccls. or 83/163.ccls. or 83/164.ccls. or 83/165.ccls. or 83/166.ccls.)
This will show what classes derive from the input. Ex: entering 43/42.24 shows the derived classes and the search that can be used to find patents or patent applications in those subclasses.
