We study the problem of computing an equitable 2-fan for three masses distributed on the 2-sphere The existence of an equitable 2-fan was shown by Bárány and Matoušek [3] The contribution of this paper is two-fold (i) We prove the existence of an infinite set of equitable 2-fans (ii) We present an efficient algorithm for finding an equitable 2-fan when the mass distributions are discrete, i.e finite sets of points Both (i) and (ii) can be easily extended to mass distributions in the plane instead of the sphere.
