Let n ...,riN be integers > 2, and let x e X be an isolated two-dimensional complex singularity whose dual intersection graph is a star with central weight 1 and with weights n, on the arms. Then X is locally the cone on a homology 3-sphere if and only if 2 n l + l n 7 l l AM suc ^ un ^ fraction expressions for 1 are given for N < 7, and properties of such sequences A?, are discussed in general.
