Hi there, On the up and up in mathematica I got stuck with trying to define a function f[a,b,c,d] that satisfies the symmetries: f[a,b,c,d] = f[b,a,c,d] and f[a,b,c,d] = f[a,b,d,c] Can anyone help? Note: These are the only symmetries I want it to satisfy, Orderless is too much freedom. Thanks Vlad. -- ___________________________ Vlad.Fridkin at anu.edu.au || ||| || ||| || ||| || ||| http://wwwmaths.anu.edu.au/~vxf661/Vlad_Fridkin.html
