Dear Mathematica friends, I have the following problem. Working in tensorial algebra I wondering if exist a package of rules able to a "clever" managing of the vector components. As example able to recognize that {-b3c2+b2c3, b3c1+b1c3, -b2c1+b1c2} is Cross[b,c] and many others to a better lecture of long expression. A simple rule, just for this, is not enough, I need a package the contain all! Thank you in advance, Ramiro PhD.
