We have the following indirect implication of form equivalence classes:
Implication | Reference |
---|---|
181 \(\Rightarrow\) 8 | clear |
8 \(\Rightarrow\) 353 |

Here are the links and statements of the form equivalence classes referenced above:
Howard-Rubin Number | Statement |
---|---|
181: | \(C(2^{\aleph_0},\infty)\): Every set \(X\) of non-empty sets such that \(|X|=2^{\aleph_0}\) has a choice function. |
8: | \(C(\aleph_{0},\infty)\): |
353: | A countable product of first countable spaces is first countable. |
