On primitive/seifert-fibered constructions

J. Dean introduced the notion of primitive/Seifert-fibered knots and constructions to explain how Dehn surgeries on knots produce small Seifert fibered manifolds. We determine non-hyperbolic, primitive/Seifert-fibered knots, and show that for such knots any integral small Seifert fibered surgery arises from a primitive/Seifert-fibered construction. We also show that any 2-orbifold S-2(n(1),n(2),n(3)) with a pair of indices coprime becomes the base orbifold of a, Seifert fibered manifold obtained by Dehn surgery on a hyperbolic, primitive/Seifert-fibered knot it S-3.
