Abstract

We show how to deal with the case where the vanishing levels of a C-sequence do not cover a club. As an application, we prove that the conclusion of Theorem D from our preprint holds true also for kappa that is a subtle cardinal. Time permits, we shall also point out how to get a long decreasing and increasing chains of Aronszajn lines.
