Abstract
We restrict our discussion to the orientable category. For g > 1, let OEg be the maximum order of a finite group G acting on the closed surface Σg of genus g which extends over.S3; Σg), for all possible embeddings Σg S3. We will determine OEg for each g, indeed the action realizing OEg. In particular, with 23 exceptions, OEg is 4(g + 1) if g ≠ k2 or 4 (√g + 1)2 if g = k2, and moreover OEg can be realized by unknotted embeddings for all g except for g = 21 and 481.
