Have a look at "Add-ons & Links / Standard Packages / Algebra / SymmetricPolynomials" http://documents.wolfram.com/mathematica/Add-onsLinks/StandardPackages/Algebra/SymmetricPolynomials.html In[1]:= Needs["Algebra`SymmetricPolynomials`"] SymmetricReduction[(x + y)^2 + (x + z)^2 + (z + y)^2, {x, y, z}] Out[2]= 2 {2 (x + y + z) - 2 (x y + x z + y z), 0} Regards, Jean-Marc
