[edit] Infinite Sets in AST

... all sets are finite (though some are "nonstandard finite" 
and externally actually infinite, and there are also classes
which can be infinite even internally) in AST. ...

What do you mean by "externally" and "internally" infinite? There is an infinite set defined in AST as a set containing a proper class as its subclass. --Gogino 05:32, 2 November 2006 (UTC)
