I will discuss the global structure of gauge groups in the framework of higher-form symmetries. In this formulation, consistency conditions on allowed non-simply connected groups can be phrased in terms of anomalies, which in supersymmetric theories in 6d and 8d are related to arithmetic properties of elliptic fibrations via F-theory compactifications. I will highlight the relationship between these arguments and ideas of the Swampland program.
