Résumé :
A remarkable sequence of polynomials is considered. These polynomials in q describe in particular the number of solution to the equation X2=0 in triangular matrices over a field with q elements. They have at least three other important interpretations and a conjectural explicit expression in terms of the entries of the Catalan triangle.
