Abstract

We find out that both the matrix and the operator CPT groups of the spin-3/2 field (with or without mass) are respectively isomorphic to D4Z2D_4\rtimes\mathbb{Z}_2 and Q×Z2Q\times\mathbb{Z}_2. These groups are exactly the same groups as for the Dirac field, though there is no a priori reason why they should coincide.
