Abstract
Within the spinorial version of the Cartan structure formulas with the built‐in (complex) Einstein vacuum equations some closed semi‐Einsteinian substructures are isolated and discussed. Then the idea of semigraviton is introduced, and its relationship to Penrose’s nonlinear graviton is described.Keywords
