Talk:Finite topological space

Untitled
Why does it say that usually only infinite spaces are of interest? This is true perhaps in the field topology but hardly in the use of topological spaces(!). — Preceding unsigned comment added by 213.103.219.58 (talk) 19:31, 18 October 2011 (UTC)

What's the major industrial application of topological space or in social science?

Topologies On Spaces With 4 Points
There is a list of inequivalent topologies on four unlabeled points in http://www.math.uchicago.edu/~may/MISC/FiniteSpaces.pdf Problem 3.3. It is also possible to independently verify that they are indeed topologies, they are not mutually equivalent modulo relabeling, and there should be only 33 of them. — Preceding unsigned comment added by Josh Liu (talk • contribs) 23:48, 24 September 2016 (UTC)


 * At this time, this article contains a list of these 33 inequivalent topologies on four points. 67.198.37.16 (talk) 21:34, 17 November 2023 (UTC)
