If you mean "do they have something in common" then they do, in that each can be approached as a limit of finite numbers. But there are also many other ways in which they differ. For instance, alephnull counts the elements of certain sets, and positive real infinity does not. Alephnull is not a maximal element in the calss of cardinales (there is none), whereas positive real infinity is maximal in the closure of the reals. Good Hunting
