I am very new at this. I could not get Juan's excellent idea to work in Mathematica 4. However, I got it to work with a slight change: (* z=Letters, n=numbers *) In[2]:= z={a,b,c};n={2,5,4} ; In[6]:= MapThread[Table, {z, List /@ n}] // Flatten Out[6]= {a,a,b,b,b,b,b,c,c,c,c} = = = = = = = I liked Andrzej idea also. I noticed that if you change "List" to "Join" then perhaps you can remove the "Flatten" command. In[9]:= Inner[Table[#1, {#2}] &, z,n,Join ] Out[9]= {a,a,b,b,b,b,b,c,c,c,c} - - - - - Dana DeLouis -- "merkat" <cabanc at hotmail.com> wrote in message news:a1gv6a$n6n$1 at smc.vnet.net... > Hi , > > How do I multiply the number of elements in a list? > I have the lists: > {a,b,c} and > {2,5,4} > > the result should be: > {a,a,b,b,b,b,b,c,c,c,c} > > Merkat >
