Use the links above or do an advanced search in ppubs for:
(166/285.ccls. or 166/286.ccls. or 166/287.ccls. or 166/288.ccls. or 166/289.ccls. or 166/290.ccls. or 166/291.ccls. or 166/292.ccls. or 166/293.ccls. or 166/294.ccls. or 166/295.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.
