We have the following indirect implication of form equivalence classes:

283 \(\Rightarrow\) 283
given by the following sequence of implications, with a reference to its direct proof:

Implication Reference
283 \(\Rightarrow\) 283

Here are the links and statements of the form equivalence classes referenced above:

Howard-Rubin Number Statement
283:

Cardinality of well ordered subsets:  For all \(n\in\omega\) and for all infinite \(x\), \(|x^n| < |s(x)|\) where \(s(x)\) is the set of all well orderable subsets of \(x\).
