I know it's been a week, but I checked and no one else has corrected this.

It is not correct, regardless of how many times it is said.

A set can be ordered or unordered.  What makes it a set is that it does not 
contain more than one item with the same value.  Note that the determination 
of value is fundamental to the semantics of the set.
