User blog comment:TheGoogologist/Hunt for the Largest Number: Part 1/@comment-35470197-20190308124852

Unfortunately, your number is ill-defined because FOOT is ill-defined. In order to avoid such non-sense, it is better to use only functions which you completely understand.

Also, such a naive combination of known large functions is not regarded as a new original work in googology community, because you can post \(N + 1\) for any known large number \(N\).

In addition, you have not defined \(NV\) and \(FNV\) at this blog post yet. When you update it, you need to specify what they mean. Stating "FNV(n) can extend infinitely" does not yield any defining sentence.
