【 摘 要 】

There are two sets of four-by-four matrices introduced by Dirac. The first set consists of fifteen Majorana matrices derivable from his four γ matrices. These fifteen matrices can also serve as the generators of the grouprespectively. This allows us to interpret Feynman’s rest of the universe in terms of space-time symmetry.
