Anti-basis theorems for higher Aronszajn lines, part 7
We prove that for every regular uncountable cardinal lambda, if there exists a lambda^+-Aronszajn line, then there exists one with no lambda^+-Countryman subline. We have already seen the proof for the case that is lambda is non-ineffable. Today, we shall give a separate proof for ineffables.
