Would a Clebsch Gordon tensor, which forms spin networks, used in loop quantum gravity, quantum chemistry and anything with global SU(2) symmetry be useful?
I have implemented this locally as an extension of the Tensor class. I can do a PR if you think it would be a nice feature.
I have not got around to implementing the algorithmic rewrites but it would be interesting to see how much of this is captured in Quimb's internal rewrite system.
