Mathcad is like a numerical solution version of macsyma with a nice equation porcessor with wysiwyg appearance, etc. it runs on PCs. Mathematica would be real nice… Clebsch-Gordan coeff.s would be useful for those physical chemistry dudes (or chem. physics!) who actually need the values, which means that they will probably be nasty to figure anyway. for simple systems, it is enough to know that they exist, without actually evaluatoing them…
