Different Types of Arahants

[Seeker12]

I seem to remember reading somewhere that in the early schools, there was some categorization of types of arahants, with some of them actually taking birth in subsequent lifetimes or something similar. I don't believe that modern Theravada discusses this at all.

Does this ring a bell for anyone? Any additional information by chance?

Thanks in advance.

Any additional info appreciated, if anyone has any.
