✦ Synopsis
We make use of the notion of 'doubled fixed point' in the graph of an exceeding mapping, to give new combinatorial interpretations (a) for the Euler finite-difference tableau relating the sequence n! to the sequence of derangement numbers, and (b) for the Seidel tableau generating the Genocchi numbers of first and second kind. Further consequences are derived for the combinatorial theory of Genocchi numbers and allied polynomials. * Corresponding author.
' Le lecteur nous excusera de ne pas donner la rbfkrence pr8cise. Signalons que le tableau d'Euler est orient& diff&remment et ne comporte pas notre 0-iBme colonne, celle des dkrangements.

In [2-J Dumont stated several conjectures about some symmetric polynomial sequences which are the refinements of the Genocchi numbers. In this paper we shall prove all of his conjectures. We first show that some special cases of his main conjecture can be readily derived from a result of Wall and th

In this paper , we propose to study the expansion of two continued fractions of Jacobi type and Stieltjes type into series . We also propose new q -Catalan numbers and give a new combinatorial interpretation of Carlitz's q -Catalan numbers .
