Hi, just a couple of notes , you seem to be using the lunate epsilon instead of the more traditional lower case greek epsilon, that one is more commonly found in logic and predicate notations.

also, the examples of your epsilons could  work with ordinals and not just finite numbers, your  j+1  method works for λ+1, and your ω method works for λ where λ is any limit ordinal
