On Closed Unbounded Sets Consisting of Former Regulars
A method of iteration of Prikry type forcing notions as well as a forcing for adding clubs is presented. It is applied to construct a model with a measurable cardinal containing a club of former regulars, starting with $o(\kappa) = \kappa + 1$. On the other hand, it is shown that the strength of above is at least $o(\kappa) = \kappa$.
