Comment to Comment on Cartesian expressions for surface and regular solid spherical harmonics using binomial coefficients and its use in the evaluation of multicenter integrals

The comments of Guseinov on our recent paper (Czech. J. Phys., 52 (2002)1297) have been analyzed critically. It is shown that his comments are irrelevant and also unjust. In contrast to his comment, it is proved that the presented formulae in our study are original and obtained independently, not by changing by the summation indices. It should be stressed that our algorithm is not affected from possible instability problems and also can be used in large scale calculations without loss of significant figures. Meanwhile, his comment on the transformation of our formula into his formula proves the correctness of our algorithm and therefore can be regarded as a nice sound of science.
