A method based on sector decomposition has been developed to calculate the double real radiation part of the process e+e-→3 jets at next-to-next-to-leading order. It is shown in an example that the numerical cancellation of soft and collinear poles works well. The method is flexible enough to include an arbitrary measurement function in the final Monte Carlo program, such that it allows one to obtain differential distributions for different kinds of observables. This is demonstrated by showing three-, four- and five-jet rates at order αs 3 for a subpart of the process.
