where Ea is a direct sum of irreducible G-modules of highest weight 2. Here we consider the conjugating representation in arbitrary characteristic and prove the appropriate version of Richardson's Theorem (under small, and almost certainly unnecessary, characteristic/root-system restrictions). One can no longer decompose A (G) into homogeneous components but instead we prove the existence of an ascending
