We have the following indirect implication of form equivalence classes:
| Implication | Reference |
|---|---|
| 133 \(\Rightarrow\) 340 | note-157 |
| 340 \(\Rightarrow\) 341 | clear |
Here are the links and statements of the form equivalence classes referenced above:
| Howard-Rubin Number | Statement |
|---|---|
| 133: | Every set is either well orderable or has an infinite amorphous subset. |
| 340: | Every Lindelöf metric space is separable. |
| 341: | Every Lindelöf metric space is second countable. |
