Using an obstruction based on Donaldson’s theorem on the intersection
forms of definite 4-manifolds, we determine which connected sums of
lens spaces smoothly embed in S4. We also find constraints on the Seifert invariants
of Seifert 3-manifolds which embed in S4 when either the base orbifold
is non-orientable or the first Betti number is odd. In addition, we construct
some new embeddings and use these, along with the d and μ invariants, to
examine the question of when the double branched cover of a 3 or 4 strand
pretzel link embeds.
