We have the following indirect implication of form equivalence classes:
| Implication | Reference |
|---|---|
| 202 \(\Rightarrow\) 91 | note-75 |
| 91 \(\Rightarrow\) 79 | clear |
| 79 \(\Rightarrow\) 369 | clear |
Here are the links and statements of the form equivalence classes referenced above:
| Howard-Rubin Number | Statement |
|---|---|
| 202: | \(C(LO,\infty)\): Every linearly ordered family of non-empty sets has a choice function. |
| 91: | \(PW\): The power set of a well ordered set can be well ordered. |
| 79: | \({\Bbb R}\) can be well ordered. Hilbert [1900], p 263. |
| 369: | If \(\Bbb R\) is partitioned into two sets, at least one of them has cardinality \(2^{\aleph_0}\). |
