Interesting:

(...) works as a countable ordinals

(((...))) without [] inside is tetration of omega with epsilon as limit

[...] works as an uncountable ordinal (that is why noticed [ ] never on the outside)

([...]) works as Buchholz psi-function with an uncountable argument

[(..)] works as countable ordinals-th element of fundamental sequense of uncountable ordinal

Deedlit reached epsilon using parentheses as an ordinal emulator and natural numbers as FGH-argument: N|On. In egg notation no natural numbers, amount of rightmost parentheses pairs denotes natural number as unary notation.

Deedlit correctly noticed that an active element is rightmost element and then only brackets. In Wythagoras work this fact seems not defined
