[REOPENED]

A new user asked [an interesting question on Tychonoff spaces](http://mathoverflow.net/questions/142128/is-there-a-tychonoff-space-x-of-cardinality-not-of-the-form-2-alpha-such-th/142134#142134), and then proceeded to delete it after it was answered. But I don't see any reason for it to be deleted, so let's reopen it.
