The number of orientable small covers over cubes. (English) Zbl 1198.37074

Summary: We count orientable small covers over cubes. We also get estimates for \(O_{n}/R_{n}\), where \(O_{n}\) is the number of orientable small covers and \(R_{n}\) is the number of all small covers over an \(n\)-cube up to the Davis-Januszkiewicz equivalence.
