Abstract To date. the best effort made to simply determine the Coulomb branch global symmetry of a theory from a 3d N $$ \mathcal{N} $$ = 4 quiver is by applying an algorithm based on its balanced gauge nodes. This often gives the full global symmetry. but there have been many cases seen where it instead gives only a subgroup. https://www.chiggate.com/shades-eq-09gi-hamptons-supply/
