I am just thinking from the perspective of students taking the course who may not be acquainted with diagrammatic techniques. And yes, for $B_k$ with HS inner product I think that's how the diagrammatic proof would look simplest. I was just wondering if there are more direct method without, as you say, using thousands of indices of brute force computation (which would amount to taking the diagram and translate them literally). If there is none I am happy with it. | |

And what is wrong with a diagrammatic proof -- those can usually be easily rewritten without resorting to diagrammatic techniques, unless there are dozens of indices. | |
