  The Calogero model is a one-dimensional quantum integrable system with
inverse-square long-range interactions confined in an external harmonic well.
It shares the same algebraic structure with the Sutherland model, which is also
a one-dimensional quantum integrable system with inverse-sine-square
interactions. Inspired by the Rodrigues formula for the Jack polynomials, which
form the orthogonal basis of the Sutherland model, recently found by Lapointe
and Vinet, we construct the Rodrigues formula for the Hi-Jack (hidden-Jack)
polynomials that form the orthogonal basis of the Calogero model.
