A three-loop calculation is presented for the jet multiplicity of produced slightly-off-shell gluons for a pure Yang-Mills theory. Planar and non-planar graphs are found to be equally important in an axial gauge. If the three-loop calculation is indicative of what happens at higher orders n (Q2) ∝ exp {[( 2CAπb ) 1 n Q2]1 2} where CA= 3 and b = (33 − 2nf) 12π in QCD.
