N2 - Solving the renormalization group equations analytically by iterations, we calculate the electric dipole moment (EDM) of the neutron in the MSSM with [Formula presented]-conserving soft-breaking parameters for the case of three and four generations. For the three-generation case we resolve the apparent discrepancies between order-of-magnitude estimates and numerical calculations existing in the literature. The nonvanishing result arises in first order in the renormalization group coefficient [Formula presented] The EDM of the neutron does not exceed [Formula presented] in this case. For the four-generation case we show that there is a significant enhancement which renders the EDM of the neutron at a measurable level of [Formula presented]
