How does having order make a set specific? What do you even
mean by 'specific'? Consider the set of students taking a given
course in a given semester. There is a very specific set of students
taking the course I am teaching this semester. There are several
different ways that the set can be ordered and often there is no need
to consider any order when discussing the set. This
set definitely has a cardinality.
