> \(\eta\) is anything it could even mean that an alpha after it is in a power tower or in another function or in a subscript

What do you mean? Is \(\eta\) an ordinal? Or is it a function symbol?

When is \(\eta \alpha\) a limit ordinal? Since you defined \(\Theta(\eta \Omega)\) in a distinct way, \(\eta \Omega\) is not a limit ordinal, right?
