I implemented PsiCubed’s letter notation for The Modding Tree OmegaNum. This implementation uses the letters E, F, G, H, and J, which goes all the way to the limit of OmegaNum.

I based this on the number formatting code for ducdat0507’s Communitree (where you can replace NumberFormating.js with this to use the implementation), but it can be used for other mods with OmegaNum too.
