Recovering a group from few orbits
Dustin G. Mixon, Brantley Vose · 2024-11-26 · via cs.IT updates on arXiv.org

For an unknown finite group $G$ of automorphisms of a finite-dimensional Hilbert space, we find sharp bounds on the number of generic $G$-orbits needed to recover $G$ up to group isomorphism, as well as the number needed to recover $G$ as a concrete set of automorphisms.
