What "help", specifically, are you needing? You've gone to your local library and borrowed a book or two on this topic, and / or found various web sites on "symmetry", right?

So... what now? Where are you stuck? :?:

Please be specific, keeping in mind that the volunteers here do not do research or write papers for posters. Thank you!
