Okay.

So what, exactly, does the ordinal ω2CK refer to? Is there an intuitive way to grasp what it means (similar to they way ω1CK is the limit of ordinary TM's)?

Or putting it differently: What kind of oracle is required to reach ω2CK? I'd like to see a function similar to ordinary BB's that can be attributed an ordinal strength of ω2CK.
