Abstract
The formulae of the relativistic products are found S=1 Barut-Muzinich-Williams matrices. They are analogs of the well-known Chisholm-Caianiello-Fubini identities. The obtained results can be useful in the higher-order calculations of the high-energy processes with S=1 particles in the framework of the 2(2S+1) Weinberg formalism, which recently attracted attention again.
