User blog comment:Ynought/Gamma function redefined/@comment-35470197-20190423213849

As I mentioned for your blog post on a catching function, "FGH" and "SGH" do not work unless you fix a system of fundamental sequences. This is one of the most difficult part because we need some ordinal notation or something like that in order to define a system of fundamental sequences for sufficiently large countable ordinals. Therefore \(\gamma\) is ill-defined.
