We have the following indirect implication of form equivalence classes:
Implication | Reference |
---|---|
101 \(\Rightarrow\) 100 | clear |
100 \(\Rightarrow\) 369 |

Here are the links and statements of the form equivalence classes referenced above:
Howard-Rubin Number | Statement |
---|---|
101: | Partition Principle: If \(S\) is a partition of \(M\), then \(S \precsim M\). |
100: | Weak Partition Principle: For all sets \(x\) and \(y\), if \(x\precsim^* y\), then it is not the case that \(y\prec x\). |
369: | If \(\Bbb R\) is partitioned into two sets, at least one of them has cardinality \(2^{\aleph_0}\). |
