Form equivalence class Howard-Rubin Number: 1
Statement:
For every \(T_2\) space \((X,T)\) and every subbase \(\cal B\) for \(X\), if \(\cal C\) and \(\cal D\) are cellular families of \(X\) included in \(\cal B\), then there is a cellular family \(\cal E\subseteq\cal B\) such that \(\cal C\) and \(\cal D\) are equipollent to subsets of\(\cal E\).
