We have the following indirect implication of form equivalence classes:
| Implication | Reference |

| 118 \(\Rightarrow\) 118 | Lattice Theory (3rd edition), Birkhoff, 1967, page 241 |
Here are the links and statements of the form equivalence classes referenced above:
| Howard-Rubin Number | Statement |
|---|---|
| 118: | Every linearly orderable topological space is normal. Birkhoff [1967], p 241. |
