Abstract
The NNLO QCD corrections to the e+e- 3 jets can be decomposed according to their colour factors. Out of the seven colour factors, three are of QED-type: 1/N2, NF/N and NF2. We use the antenna subtraction method to compute these contributions, providing complete expressions for the subtraction terms in NF/N and NF2.
