CP nonconservation in the Kobayashi-Maskawa model with four generations

A convenient parametrization of mixing matrix has been sugqested. It is shown, that the existence of the fourth generation of fermions can explain both the observed value of a CP-invariance parameter epsilon and the epsilon'/epsilon ratio of any sign, but only if the admixture of the fourth generation to the first two is not less, than that of the third one. In the Bsub(s)sup(0)-anti Bsub(s)sup(0) system the fourth generation can cosiderabl.y increase the CP-odd mixing
