What word can you use to describe a "set with repeated elements"

[fleazo]

The reason I have that in quotes is because by definition, elements in a set must be unique, and there is no concept of repeated elements. I was just wondering if there is a word to describe such an object - namely, a collection of "items" (or whatever you'd like to call them), where you might have repeated elements. Example : {2,2,5,1,4}. What word could I use to describe this?

Thank you

Try "multiset"

Thank you! Exactly what I was looking for!

Usually a set is distinguished by its elements alone, so , e.g., {2,2}={2}={2,2,2}, etc. If you want to distinguish different copies of an element, you can write something like {2,2'} or something similar.
