  The transition between two conceptionally different solution procedures for
general axisymmetric tangential contact problems with arbitrary laoding
histories under Hertz-Mindlin assumptions is demonstrated, namely J\"ager's
superposition solution and the method of dimensionality reduction. Both finite
and ininite superpositions of Cattaneo-Mindlin basis functions are considered.
It is shown how the weights in the superposition solution can be easily
obtained from the displacements in the MDR model.
