Researchers have developed a new algorithm for reconstructing rational-valued functions on finite Abelian groups using higher-order autocorrelations. This method has applications in fields such as X-ray crystallography, computer vision, and pattern recognition. The study establishes that autocorrelations up to order $3r+3$ are sufficient for determining the data, where $r$ is the rank of the group. It also identifies cases where autocorrelations up to order $3r+2$ are insufficient, providing a sharp upper bound on the separating degree of the regular representation of a finite Abelian group. AI
