| Jul 29, 2019 at 15:58 | comment | added | M. Winter | Thank you for this nice example. I am indeed mainly interested in real irreducible represenations, so this fits perfectly. Do you see any immediate reason why the dimension of such an irreducible representation of multiplicity $\ge 2$ has to be even? I would be highly interested in an example of odd dimension if you know of one. | |
