Simplifying the large-mass expansion of Feynman integrals

We show how the well-known large-mass expansion of Feynman integrals can be simplified to obtain more terms of the expansion in analytic form. Expansion of two-loop four-point Feynman integrals that contribute to the \(H \to ggg\) process is used as an example.
