Abstract:
An algorithm for finding the best cubature formulas (in a sense) on the sphere that are invariant under the transformations of the cyclic rotation groups $C_{kh}$ is described. This algorithm is applied for finding the parameters of the best cubature formulas of 19th and 31st orders of accuracy.
Keywords: numerical integration, invariant cubature formulas, invariant polynomials, cyclic rotation group.
