Merry Xmas, Joyeux Noël,

AND , ET ,

xy-yx+z

z est un nombre entier très remarquable, relié à "la constante
de Ramanujan" R: z est le carré de (ln R)/p. R est très proche d'un nombre entier N+1=M3+744, où M est un multiple de 10. Enfin, les trois derniers chiffres de l'écriture (décimale) de N sont y, y-x et x.
