Let el,...,~ be pairwise prime integers with a. > i for each n i i. Let Z = ~ (el,...,~n) be the Seifert fibered homology 3-sphere with singular fibers of orders ~i .... '~ " By iN-R] (see also iN1], n iN2]), Z has a unique orientation making it the link of a complex surface singularity (V(el,...,en),p) ; we give E this orientation. This is also the unique orientation for which E bounds a plumbed 4-manifold with negative definite intersection form. A minimal such plumbing (i.e. admitting no (-l)-blow down) is unique. It is given by the following plumbing diagram (which is also the minimal good resolution diagram for the above singularity):
