Show affiliationsThe authors describe an algorithm for constructing a good polynomial basis for the relative invariants associated with any real representation of a crystallographic point group (CPG). The novelty here is the universality of the algorithm. It depends on the fact that a typical real representation of a CPG has a particularly simple form and has a close relationship to a small number of low-dimensional matrix groups whose invariants are known and well behaved.
