We present numerical results for the two-loop virtual amplitude entering the NNLO corrections to Higgs boson production in association with a top quark pair at the LHC. We focus on the quark initiated channel and the colour factors containing closed quark loops, as a proof of concept to describe our method. Results for the finite part of the two-loop amplitude are visualized as functions of phase space variables.
