Subcomponents $\psi_{4,1}^{(2d)}$ and $\psi_{3,0}^{(2c)}$ of the angular   Fock coefficients: Explicit analytic representation
  The Fock expansion [1] describes the $S$-state wave function of the two-electron atomic system in the vicinity of the triple coalescence point. The present work constitutes the additional appendix to our paper [2] devoted to refinement and further development of calculation of the angular Fock coefficients of the Fock expansion. We derive the explicit analytic expressions for the complicated subcomponents $\psi_{4,1}^{(2d)}$ and $\psi_{3,0}^{(2c)}$ of the angular Fock coefficients. An unusual method of using the Wolfram Mathematica was applied.
