WebApr 2, 2015 · I'm pretty sure the distinction between List and Set exists in computer science because people wanted a term to describe a sequence of data (a "List") versus an unordered, unsequenced "Set", and because many lists are implemented in a way such that they are logically described as a List. WebOrder topology. In mathematics, an order topology is a certain topology that can be defined on any totally ordered set. It is a natural generalization of the topology of the real numbers to arbitrary totally ordered sets. If X is a totally ordered set, the order topology on X is generated by the subbase of "open rays".
