Mathematica 5.0.1 on Windows 2000 MathGroup: In my study of Flatten, the Mathematica Book gives this example ... You can use Flatten to "splice" sequences of elements into lists or other expressions. In[5]:= Flatten[ {a, f[b, c], f[a, b, d]}, 1, f ] Out[5]= {a,b,c,a,b,d} I modified In[5] as follows ... In[1]:= Flatten[ { {a, f[b, c], f[a, b, d]}, {g, f[e, g]} }] Out[1]= {a, f[b, c], f[a, b, d], g, f[e, g]} I don't see why adding {g, f[e, g]} as a second list to the In[5] example unflattens Flatten's answer. What am I misunderstanding? Thanks. Harold
