Hi,
I have found a very strange result in SUNSimplify.
If I do SUNSimplify[ SUNDelta[i,j] SUNDelta[i,j]], I would expect the result to be N (it is just the trace of delta unless I really missed the point of what SUNSimplify does and what SUNDelta is).
However I get as a result
2 CA CF
that is quite strange.

Another issue I encountered trying to do computations with color indeces is that I cannot get rid of \\\\Delta[1,1] or to substitute it with 1, and so on…

Am I missing something?
Thanks
