The short story "A Subway Named Moebius" is also in a book named "Fantasia Mathematica", a collection of fiction, poetry, etc. (not all SF) about mathematics. For instance, there is a story by Clarke (?) about a house built in the shape of an unfolded tesseract that folds up in an earthquake. Most everything in the book is very entertaining. You can usually find it in the non-fiction math section of your local library. --Dan
