By definition, the mode is the number that occurs most often in a list. You could argue that a list would have no mode if 

(a) The list had no elements ( an empty set)

(b) All items in the list were unique; that is, there were no duplicates (such as the list 1,3,4,5,6,7,8 )


In the latter case, they are all modes.
