Abstract
The repulsive energy of three helium atoms is calculated using the valence bond method. A great reduction of the required number of exchange integrals is found to be possible using group theoretical arguments. It is found that the effect of nonadditivity is negligible for the internuclear distances involved in most physical problems.Keywords
