User blog comment:P進大好きbot/What is the greatest ordinal notation now?/@comment-31966679-20180623154722

I don't know because the only ones I know is the Slow Growing Hierarchy, the Hardy Growing Hierarchy, and the Fast Growing Hierarchy. But I wonder if my ordinal notation could be on the top 100 list. Probably not, but take a look at my blog post about my ordinal notation by clicking my profile name and going to my blog posts and scrolling down until you see the blog post.
