| Jun 27, 2018 at 9:41 | comment | added | Matthew Daws | Doesn't Andreas say that $\chi^{2n}$ is golden if and only if $n=0$ or $1$. So $\chi^4$ is your counter-example... I think? | |
| Jun 27, 2018 at 8:44 | comment | added | MSMalekan | But $\chi^2=2+\delta_2+\delta_{-2}$ is golden so this is not the counterexample! | |
