Abstract
We consider a two-dimensional -model with discrete icosahedral/dodecahedral symmetry. Using the perturbative renormalization group, we argue that this model has a different continuum limit with respect to the O(3) model. Such an argument is confirmed by a high-precision numerical simulation.
