Based on these data, we devise a method to determine the global gauge group structure including all <math><mi>U</mi><mo>(</mo><mn>1</mn><mo>)</mo></math> factors. The key observation is that, while the physical states correspond to vectors in the momentum lattice, the gauge group topology is encoded in its dual. Interpreting a nontrivial <math><msub><mi>\u03c0</mi><mn>1</mn></msub><mo>(</mo><mi>G</mi><mo>)</mo><mo>\u2261</mo><mi>Z</mi></math> for the non-Abelian gauge group <math><mi>G</mi></math> as having gauged a <math><mi>Z</mi></math> 1-form symmetry, we also prove that all CHL gauge groups are free of a certain anomaly [1] that would obstruct this gauging. We verify this by explicitly computing <math><mi>Z</mi></math> for all 8D CHL vacua with <math><mrow><mi>rank</mi><mo>(</mo><mi>G</mi><mo>)</mo><mo>=</mo><mn>10</mn></mrow></math>. Since our method applies also to <math><msup><mi>T</mi><mn>2</mn></msup></math> compactifications of heterotic strings, we further establish a map that determines any CHL gauge group topology from that of a \u201cparent\u201d heterotic model."
