| Jun 24, 2014 at 15:10 | comment | added | Kay McHamilton | S., I agree that's a natural and beautiful bijection, but it is not the map I am asking about. | |
| Jun 24, 2014 at 8:20 | comment | added | S. Carnahan♦ | I was under the impression that the bijection with characters was more natural, since the tensor product with the 2-dimensional representation yields the extended Dynkin graph adjacency relation. | |
