  The multi-indexed Laguerre and Jacobi polynomials form a complete set of
orthogonal polynomials. They satisfy second-order differential equations but
not three term recurrence relations, because of the 'holes' in their degrees.
The multi-indexed Laguerre and Jacobi polynomials have Wronskian expressions
originating from multiple Darboux transformations. For the ease of
applications, two different forms of simplified expressions of the
multi-indexed Laguerre and Jacobi polynomials are derived based on various
identities. The parity transformation property of the multi-indexed Jacobi
polynomials is derived based on that of the Jacobi polynomial.
