Subsingletons and genuine subsingletons

Abstract: We introduce the notion of `genuine' subsingleton, which is relevant both to my investigation of Zorn's Lemma and my study of Vermeulen-finitary algebraic structures. Proofs from my last two talks will be improved and/or clarified, and at least one converse will be added.
