Is there a way to label an object in Cadabra?
Suppose I wanted to define some tensor Tabcef, gives it some properties (e.g. make some indices antisymmetric or something, give it some rules...). Could I then use multiple copies, each having a different label?
Or in the very simple case, could I do something like define a momentum vector which has one vector index and one label, so I can have e.g. p1⋅p2 and similar?
Thanks!
