The first one is the method of covariant calculations for the amplitudes of processes with polarized Dirac particles. The second one connects with the possibility to reduce the expressions for the traces of products of ten and more Dirac gamma-matrices.9 pages, LaTeX, talk presented at the XVIII Workshop on High Energy Physics and Field Theory.
