An interactive FORTRAN code for determining the representations of U(3) that occur in a representation of U(N) is introduced. The U(N) -' U(3) chain is the basic group structure of the isotropic oscillator in three dimensions. In particular, N (n + lXn + 2)/2 is the degeneracy of the shell with n qu
