abstract = {Exact numerical results of the interacting boson model Hamiltonian along the integrable line
from U(5) to O(6) are obtained by diagonalization within boson seniority subspaces. The matrix
Hamiltonian reduces to a block tridiagonal form which can be diagonalized for large number of
bosons. We present results for the low energy spectrum and the transition probabilities for systems
up to 10000 bosons, which confirm that at the critical point the system is equally well described by
the Bohr Hamiltonian with a  4 potential.},
