Implications

We have the following indirect implication of form equivalence classes:

419 \(\Rightarrow\) 419
given by the following sequence of implications, with a reference to its direct proof:

Implication Reference
419 \(\Rightarrow\) 419

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

Howard-Rubin Number Statement
419:

UT(\(\aleph_0\),cuf,cuf): The union of a denumerable set of cuf sets is cuf. (A set is cuf if it is a countable union of finite sets.)

419:

UT(\(\aleph_0\),cuf,cuf): The union of a denumerable set of cuf sets is cuf. (A set is cuf if it is a countable union of finite sets.)
