Use the links above or do an advanced search in ppubs for:
(105/150.ccls. or 105/151.ccls. or 105/152.ccls. or 105/153.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.
