  In a previous paper we derived equivalence relations for pseudo-Wronskian
determinants of Hermite polynomials. In this paper we obtain the analogous
result for Laguerre and Jacobi polynomials. The equivalence formulas are richer
in this case since rational Darboux transformations can be defined for four
families of seed functions, as opposed to only two families in the Hermite
case. The pseudo-Wronskian determinants of Laguerre and Jacobi type will thus
depend on two Maya diagrams, while Hermite pseudo-Wronskians depend on just one
Maya diagram. We show that these equivalence relations can be interpreted as
the general transcription of shape invariance and specific discrete symmetries
acting on the parameters of the isotonic oscillator and Darboux-Poschl-Teller
potential.
