Hi, The equations does not say much about the system before you solve them, that is, before you determine all the amplitudes t_i^a, t_ij^ab. The link is to a very nice and pedagogical introduction, so if you are going to learn CC that is exactly where I would recommend you to start. The equations that the script generates are in chapter 4 of the book, specifically: Eqs (4.59), (4.75) and (4.76).
