Seventy Topics - 6*6 = 36 paramitas

In our local group we are working with Dön Dün Chu, the 70 points (from Abhisamayalankara) by Jetsün Chökyi Gyaltsan . In I.7 (putting on the armor) the 6 paramitas are mentioned. It is said that they interlock in a cross product, meaning there are actually 36 resulting traits to consider in your practise. 1. generosity, giving of oneself (sbyin-pa) 2. virtue, morality, discipline, proper conduct (tshul-khrims) 3. patience, tolerance, forbearance, acceptance, endurance (bzod-pa) 4. energy, diligence, vigor, effort (brtson-’grus) 5. one-pointed concentration, contemplation (bsam-gtan) 6. wisdom, insight (shes-rab) Now, I have my problems understanding two things: where is the difference between n\*m and m\*n? And what is n\*n (reflexive)? I could not find any sources on that and my teacher had no time to answer this in detail. The reflexive relations only make sense to me as in "generosity *in general*" for example but I heard there is more to it. Maybe I need starting help as in how to connect each point with the others.
