Very easy:
{} or {{}} are examples of finite sets.
{a,b,c,..} or {{a,b,c,...}} are examples of infinite sets.
Ah! So the secret is in the Axiom of the Ellipses.
Seriously, though, how will you be able to identify an infinite set in this your private mathematics of yours? For that matter, how do you propose to build a set theory that even includes infinite sets?
In both cases Set (represented by the outer "{" "}" ) is not a member of itself (its existence is non-local w.r.t any collection (finite or not) of members.
This has no relevance to my question.
