We have the following indirect implication of form equivalence classes:

186 \(\Rightarrow\) 186
given by the following sequence of implications, with a reference to its direct proof:

Implication Reference
186 \(\Rightarrow\) 186

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

Howard-Rubin Number Statement
186:

Every pair of cardinal numbers has a least upper bound (in the usual cardinal ordering.)

186:

Every pair of cardinal numbers has a least upper bound (in the usual cardinal ordering.)
