The classical Lüneburg lens scattering problem has a solution ex- pressed in terms of the Whittaker and Heun functions. The difficulties of finding these functions in CAS Maple are described. The software package «Fucsh for Sage» for working with Fuchsian singular points of linear differen- tial equations is presented, in which the Maple results are verified.
