For example, Trundefined-| (n) would be a subscript Iteration of Z999,999 "n" long.. Take the last one and then transform IT into a subscript iteration of Z999,998. Eventually, you reach omega.

Subscript iteration = the way \(\zeta) is a nesting of epsilons. Then, once you reach Ea you define it as a powertower of E a-1 n high, until you reach E0 which is a powertower of omegas n high.
