It depends a lot on what you want to do with your trees. However, I find the simplest representation to be an expression, f[x,y,z,...], where f is the parent and x, y, z, etc. are children. If x, y, z, ... are atomic, then they are leaves. If they are expressions, then they are sub-trees. Then when you're done creating your tree, you can view it with an application we wrote called TreeView. http://omegaconsultinggroup.com/Products/tree ---------------------------------------------- Omega Consulting The final answer to your Mathematica needs. http://omegaconsultinggroup.com
