In this talk, we discuss ZZ production through gluon fusion at two loops, with full top mass dependence. We use a syzygy based approach for the reductions to master integrals. In order to numerically evaluate the amplitude, we express it in terms of finite integrals, which we construct out of linear combinations of divergent integrals using a new algorithm.
