Abstract
We investigate iterating the construction of , the -like inner model constructed using stationary-logic. We show that it is possible to force over generic extensions of to obtain a model of , and to obtain models in which the sequence of iterated s is decreasing of arbitrarily large order types. For this we prove distributivity and stationary-set preservation properties for countable iterations of club-shooting forcings using mutually stationary sets, and introduce the notion of mutually fat sets which yields better distributivity results even for uncountable iterations.
