Coincidence intensities of the cascade decay 31D --> 21P --> 11S of helium excited by electron impact are computed using the symbolic manipulation package Mathematica. The formulation requires the calculation of a few thousand Clebsch-Gordan coefficients and rotation matrices, which would be extremely tedious to carry out by hand. A scheme is presented as an illustrative example of a lengthy and cumbersome calculation handled by Mathematica with ease.
