    "abstract": "We consider sets of quantum observables corresponding to eutactic stars.\nEutactic stars are systems of vectors which are the lower dimensional\n``shadow\u0027\u0027 image, the orthogonal view, of higher dimensional orthonormal bases.\nAlthough these vector systems are not comeasurable, they represent redundant\ncoordinate bases with remarkable properties. One application is quantum secret\nsharing.",
