this is really odd.... In[1]:=s = {a, b, c, c, d, e, e, f, g, g, g, h, a, b} // Intersection Out[1]= {a,b,c,d,e,f,g,h} In[2]:=s = {a, b, c, c, d, e, e, f, g, g, g, h, a, b} // Union Out[2]= {a,b,c,d,e,f,g,h} In[3]:=s = {a, b, c, c, d, e, e, f, g, g, g, h, a, b} // Complement Out[3]= {a,b,c,d,e,f,g,h} I'm guessing it's use of these functions on single list of values that makes them behave like that...
