We perform a high-precision computation of the three-loop three-point formfactor of the stress-tensor supermultiplet in ${\cal N}=4$ SYM. Both theleading-color and non-leading-color form factors are expanded in terms ofsimple integrals. We compute the complete set of integrals at a specialkinematic point with very high precision using $\mathtt{AMFlow}$. Thehigh-precision leading-color result enables us to obtain the analytic form of anumerical constant in the three-loop BDS ansatz, which is previously known onlynumerically. The high-precision values of the non-leading-color finiteremainder as well as all integrals are also presented, which can be valuablefor future use.
