  A singular polynomial is one which is annihilated by all Dunkl operators for
a certain parameter value. These polynomials were first studied by Dunkl, de
Jeu and Opdam, (Trans. Amer. Math. Soc. 346 (1994), 237-256). This paper
constructs a family of such polynomials associated to the irreducible
representation (N-2,1,1) of the symmetric group S_N for odd N and parameter
values -1/2, -3/2, -5/2,... . The method depends on the use of Krawtchouk
polynomials to carry out a change of variables in a generating function
involved in the construction of nonsymmetric Jack polynomials labeled by
(m,n,0,....), m>=n.
