# Splitting up some categories

Recently, the wiki's article count had a rapid growth. Because of this, some of the categories where numbers of the same size group is located has grown quite large. In this blog post, I propose to divide these categories, an idea that has been discussed in the (possibly unofficial) Googology Wiki Discord server.

The categories we want to divide are the follows:

- Category:Up-arrow notation level (1,376 pages as of this writing)
- First divide the pentation level and hexational level numbers to their own categories. We can divide the rest if it's not enough.

- Category:Tetrational array notation level (578 pages as of this writing)
- Currently smaller than the above category, but will grow as articles for E^ numbers are created. A similar approach might be needed: divide the superdimensional array notation level numbers (\(\omega^{\omega^\omega}\) ~ \(\omega^{\omega^{\omega^\omega}}\)) to their own category, and divide the rest if not enough.

- Category:Higher array notation level (840 pages as of this writing)
- Now this is a tough one. BEAF above tetrational arrays has always been controversial about their well-definedness. Therefore, I suggest dividing it to ordinal-based categories. Here's how I think this category should be divided:

- Category:Epsilon level (\(\varepsilon_0\) ~ \(\zeta_0\))
- Category:Binary-phi level (\(\zeta_0\) ~ \(\Gamma_0\))
- Category:Finite-length phi level (\(\Gamma_0\) ~ SVO)
- Category:Higher computable numbers (SVO and above) (There hasn't been many googolisms beyond SVO so far)

- In fact, let's merge Category:Legiattic Array Notation Level and Category:Beyond Legiattic Array Notation Level into Category:Higher computable numbers, because the well-definedness of legiattic arrays and beyond is even more controversial.

What do you think?
