Abstract We perform a high-precision computation of the three-loop three-point form factor of the stress-tensor supermultiplet in N $$ mathcal{N} $$ = 4 SYM.Both the leading-color and sub-leading-color form factors are expanded in terms of simple integrals.We beefeaters triple flavor twists compute the complete set of integrals at a special kinematic point with very high precision using AMFlow.The high-precision leading-color result igora vibrance 6-12 enables us to obtain the analytic form of a numerical constant in the three-loop BDS ansatz, which is previously known only numerically.
The high-precision values of the non-leading-color finite remainder as well as all integrals are also presented, which can be valuable for future use.
