The "search hierarchy!" link will execute this search:
((164/89 <IN> CPC) <OR> (164/90 <IN> CPC) <OR> (164/91 <IN> CPC) <OR> (164/92 <IN> CPC) <OR> (164/93 <IN> CPC) <OR> (164/94 <IN> CPC) <OR> (164/95 <IN> CPC) <OR> (164/96 <IN> CPC) <OR> (164/97 <IN> CPC) <OR> (164/98 <IN> CPC))
This will show what classes derive from the input. Ex: entering 78/35 shows the derived classes and the search that can be used to find
patents in those subclasses.
