Comment on Cartesian expressions for surface and regular solid spherical   harmonics using binomial coefficients and its use in the evaluation of   multicenter integrals
  Recently published formulas for the surface and regular solid spherical harmonics and for the expansion of the product of two normalized associated Legendre functions with different centers in ellipsoidal coordinates (Telhat Ozdogan, Metin Orbay, Czech.J.Phys., 52(2002)1297) are critically analyzed. It is demonstrated that the presented in this work formulas are not original and they are available in the literature or can easily be obtained from the published in the literature formulas by changing the summation indices.
