We have the following indirect implication of form equivalence classes:

48-K \(\Rightarrow\) 48-K
given by the following sequence of implications, with a reference to its direct proof:

Implication Reference
48-K \(\Rightarrow\) 48-K Finite axioms of choice, Truss, J. K. 1973a, Ann. Math. Logic
Axiom of choice for finite sets, Mostowski, A. 1945, Fund. Math.

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

Howard-Rubin Number Statement
48-K:

If \(K\) is a finite subset of \(\omega-\{0,1\}\), \(C(WO,K)\): For every \(n\in K,\) \(C(WO,n)\).

48-K:

If \(K\) is a finite subset of \(\omega-\{0,1\}\), \(C(WO,K)\): For every \(n\in K,\) \(C(WO,n)\).
