# Notation Question

Let's say I have a set {A}. How do I denote the largest member of that set?
For example, let's say I have a solution set of discrete values. How do I denote the largest solution?

Basically, with any set, how do I denote the largest member of that set? What symbol/s do I use !?

What's wrong with something like $$max(A)$$??

That is the formal/accepted way of expressing it (the largest member of a set), right?

Do maximums differ from least upper bounds (supremums)? The definitions I found didn't clear this up. Edit: Eh, because I was going to say supremum.

AFAIK, the maximum of a set must necessarily be a member of the set as well. So for example, {1 - 1/n; n a natural} has a supremum, but no maximum.
