Ineffable Numbers are extremely large finite numbers, this is about as much as we can truly say about these numbers. There are infinitely many of them.
Definition (or as close as we can get to one)[]
Ineffable Numbers are numbers so enormously large that no kind of definition we could make would be sufficient enough, this means that that definition in itself is not sufficient, it can convey the basic idea but that is also a definition, therefore if we could write that out then ineffables are a lot larger. These numbers are also ineffable to AI and to any computer we could ever make. As we get more advanced at creating large finite numbers, ineffables will also get further away. We could never reach these numbers because if we did they wouldn't be ineffable. Even a symbol is not sufficient as that is a form of definition. Even this definition is not sufficient as no definition we can make is strong enough.
