Let be a principal ideal domain with infinite spectrum such that for every nonzero prime ideal of , the residue field is finite. Let be the quotient field of . We investigate sets of lengths in the ring of integer-valued polynomials on , . For every multiset of integers , we explicitly construct an element of with exactly essentially different factorizations into irreducible elements of whose lengths are . Furthermore, we show that is not a transfer Krull domain. These results spark off the study of sets of lengths in the rings , where is an infinite subset of .
