Since my first answer was a bit too much like everyone else's, here is one that is a little more original :) In[2]:= l1={a,b,c}; l2={2,5,4}; In[6]:= Flatten[l1^l2/.Power[x_,n_]:>Table[x,{n}]] Out[6]= {a,a,b,b,b,b,b,c,c,c,c} On Thursday, January 10, 2002, at 01:37 PM, Andrzej Kozlowski wrote: > Lots of different ways, I am sure.
