Abstract—
It is shown that C and T are related to the Clifford complex conjugation and Clifford transposition operators, and that they can be exact symmetries only in phenomena in which there are tensor quantities or only spinors or only conjugate spinors. P, CT, and CTP can be exact symmetries of the spinors. The symmetry operator iQ also exists for electrically charged spinors. This is the operator of reflection of the two Clifford basis vectors corresponding to the internal degrees of freedom of the spinors.
