Abstract We study two types of discrete operations on Coulomb branches of 3d N $$ \mathcal{N} $$ = 4 quiver gauge theories using both abelianisation and the monopole formula. We generalise previous work on discrete quotients of Coulomb branches and introduce novel wreathed quiver theories. We further study quiver folding which produces Coulomb branches of non-simply laced quivers. https://www.popularfilm.blog/
