A remarkable sequence of polynomials is considered. These polynomials in $q$ describe in particular the number of solution to the equation $X^2=0$ in triangular $n \times n$ matrices over a field ${\Bbb F}_q$ 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.
