The contribution to the eighth-order anomalous magnetic moment ($g\ensuremath{-}2$) of the electron from a set of diagrams without closed lepton loops is recalculated using a new FORTRAN code generated by an automatic code generator. Comparing the contributions of individual diagrams of old and new calculations, we find an inconsistency in โฆ
