Abstract
A connection is established between an interacting boson model (IBM) that includes bosons (IBM-3) and one that includes as well as bosons (IBM-4). The connection relies on an IBM-4 classification that breaks Wigner's SU(4) symmetry. The resulting generalized IBM-4 is relevant for studying the competition between and pairing in nuclei. Consequences for the pair structure in self-conjugate nuclei are discussed.
