We investigate the physical properties of ${G}_{2}$-symmetric integrable chains with local degrees of freedom in the fundamental representation; given the typical connection between integrability and critical points, we test the model's properties against a hypothesis of conformal-invariant long-distance behavior. Leveraging an embedding between the ${G}_{2}$ exceptional Lie algebra and $\mathrm{SU}(2)$-symmetric …
