The ${\ensuremath{\alpha}}^{4}$ contribution to the lepton $g\ensuremath{-}2$ from a gauge-invariant set of 18 Feynman diagrams containing a light-by-light scattering subdiagram internally has been reevaluated by a method independent of the previous approach. Comparison of two methods revealed a program error in the first version. Correcting this error, the contributions of …
