Diagonal 2I-Invariance Selects the Universal Spin-j Singlet and Its Casimir Correlator

For each of the five representations $\chi_{2j+1}$, $j \in \{\tfrac{1}{2}, 1, \tfrac{3}{2}, 2, \tfrac{5}{2}\}$, obtained by restricting the spin-$j$ representation of $\mathrm{SU}(2)$ to the binary icosahedral group $2I$, we prove a conditional theorem: given a bipartite carrier...
