| Apr 16, 2017 at 20:20 | comment | added | Joel David Hamkins | No, you've misunderstood @WłodzimierzHolsztyński. My hypergraphs allow, in addition to those finite edges, any collection of infinite edges. There are $2^{\aleph_0}$ many infinite edges, and so there are $2^{2^{\aleph_0}}$ many ways to form a hypergraph using them. | |
| Apr 16, 2017 at 20:07 | comment | added | Włodzimierz Holsztyński | ? -- The edges of ALL hypergraphs from the collection belotg to a countable family, namely $\ \{1\ldots n\} :n\in\mathbb N\}.\ $ Thus your collection has cardinality $2^\aleph_0,\ $ which smaller than required. Am I wrong? *** I am sure that I misinterpreted your answer. Perhaps your answer is more involved. ? | |
