“…As a result, all degrees of freedom in the gauge parameters |Λ (2)0 g0 (2,1) , |Λ (2)1 0 (2,1) are used, and the theory becomes a first-stage-reducible gauge theory with the independent parameter |Λ (1)l g0 (2,1) , l = 0, 1, in which only the component spin-tensors ψ (1)1 r , for r = 1 − 4, 6, 7, 9, ψ (1)1 t|µ , for t = 5, 8 and ψ (1)0 m|µν , ψ ′(1)0 n|µ , ψ (1)0 u|µ , ψ (1)0 v , for m = 13, 18; n = 1, 6; u = 1, 6, 9, 10, 14, 15, 21; r = 13, 18; v = 1 − 8, 11, 12, 16, 17, 19 − 21 survive. For the reducible gauge parameters |Λ l 0 (2,1) , l = 0, 1 determined by Eqs. (D.10)-(D.13) the general gauge conditions (C.12), having the form (for s max = 3) 6,11,17,18,20,23,28,29,34,35; ψ 0 t|µ , for t = 20, 23, 35; ψ 0 35|µν . (6.47)…”
