I do know any appian rule that could give you that info however, the following code returns the list of empty groups 
 
load( 
 local!listOfGroupsConstants: { 
 cons!GROUP1, 
 cons!GROUP2, 
 cons!GROUP3, 
 cons!GROUP4 
 }, 
 index( 
 local!listOfGroupsConstants, 
 wherecontains( 
 0, 
 a!forEach( 
 local!listOfGroupsConstants, 
 count( 
 getdistinctusers( 
 topeople( 
 fv!item 
 ) 
 ) 
 ) 
 ) 
 ), 
 {} 
 ) 
)
