Sage doesn't handle abstract topological spaces like this. If you worked at it, you could probably find something essentially equivalent, but it's probably better just to understand the underlying mathematics using paper and pencil. For questions like this, try http://math.stackexchange.com instead. I'm closing this question as off-topic.
