It seems that this notion of "not finite" as not equipollent with a natural
number is quite weak in E, seeing as it would also label the set

W = {0} -> {0,1} -> {0} -> {0,1} -> ...

as "infinite" in this sense, even though W is also a subset of {0,1}.
(Assuming I have correctly captured the "internal logic of E"...)
