We have the following indirect implication of form equivalence classes:

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

Implication	Reference
187 \(\Rightarrow\) 186	Set theory for the mathematician, Rubin, [1967]

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

Howard-Rubin Number	Statement
187:	Every pair of cardinal numbers has a greatest lower bound (in the usual cardinal ordering.)
186:	Every pair of cardinal numbers has a least upper bound (in the usual cardinal ordering.)
