How would one write a multiset subset of a set? So say A is a subset with multiple elements of B. I have a feeling it's not just:
$A\subset B$

by multiple I mean B={1,2,3,4}, while A={1,1,1,1,2}.

There has to be someone who did this previously. I can't be the first where this has come up.

ok, then check wikipedia
https://en.wikipedia.org/wiki/Multiset#Basic_properties_and_operations
you can probably write support(A) \subseteq B or something

A = {1,1,1,1,2} is equivalent to A = {1,2}

How about the union? so
$A\cup B = B$ .

>>13117876
As a set, yeah. Multiset have some repeated elements.
