Call a periodic maphon the closed orientable surface Σgextendable ifhextends to a periodic map over the pair (S3,Σg) for possible embeddingse: Σg→S3. The authors determine the extendabilities for all periodical maps on Σ2. The results involve various orientation preserving/reversing behalves of the periodical maps on the pair (S3,Σg). To do this the authors first list all periodic maps on Σ2, and indeed the authors exhibit each of them as a composition of primary and explicit symmetries, like rotations, reflections and antipodal maps, which itself should be interesting. A by-product is that for each eveng, the maximum order periodic map on Σgis extendable, which contrasts sharply with the situation in the orientation preserving category.
