Sets are usually considered as having cardinalities; for finite sets that
most easily represents the count of the number of elements.

For implementations in software, there are generally other ways to look
into a set, such as iterators, which also make it reasonably clear that
there are no duplicates.

And if that is unclear, look at the definitions of Bags/Multisets, which
intentionally distinguish themselves from Sets precisely on the ability
to contain duplicates.
