Hello I would like to represent with Spherical Harmonics any function with a given symmetry on a sphere. The symmetry is here the one of the 432 point group, that is with 4-fold, 3-fold and 2-fold axes of a cube. Note that I need to represent a function which is NOT centro-symmetric, that is which does NOT obey f[r] = f[-r] (thus the point group has 24 elements). I would appreciate very much a "ready-to-use" formula as I have an immediate and practical problem to solve. Many thanks Philippe Dumas
