Given a set, A, is there a word and/or symbol that means "an element of A, or an element of an element of A, or an element of an element of an element of A, or..."(adsbygoogle = window.adsbygoogle || []).push({});

By analogy with the use of the term in linguistics, I wondered if descendent might be used in this way. The only hit I found on google for the expression in the title of this post looks a bit too technical for me at the moment.

I can't tell what its definition means, but I suspect it's using the word descendent in a different sense. Incidentally, does [itex]\in \in[/itex] mean "is an element of an element of"?
