Starting from a model V ⊧ ZFC + GCH + “κ is supercompact” + “No cardinal is supercompact up to a measurable cardinal”, we force and construct a model V P such thatV P ⊧ ZFC + “κ is supercompact” + “No cardinal is supercompact up to a measurable cardinal” + “δ is measurable iff δ is tall” in which level by level equivalence between strong compactness and supercompactness holds. This extends and generalizes both [[4][A. Apter, 2014], Theorem 1] and the results of [5][A. Apter, 1997].
