Considering the same test for <math><mi>N</mi><mo>=</mo><mn>8</mn></math> supergravity leads us to discover that this theory does support nonvanishing residues at infinity starting at two loops, and the degree of these poles grow arbitrarily with multiplicity. This causes a tension between simultaneously manifesting ultraviolet finiteness\u2014which would be automatic at two loops for representation obtained by color-kinematic duality\u2014and gauge invariance\u2014which would follow from unitarity-based methods."
