Is there an operator that transform a Multiset into a set by choosing all the distinct elements? Is there a better/more accurate way to write it than this:


We denote the set $S$ by choosing the distinct elements in the Multiset $A$. I.e., $S=distinct(A)$


For example assume $A=\{2,3,3,3,5\}$ then $S=distinct(A)=\{2,3,5\}$



Multiset to set operator
[Wikipedia](https://en.wikipedia.org/wiki/Multiset) says that this operator is the *support* operator, $S=\operatorname{supp} A$.
