The so-called "Padua points" give a simple, geometric and explicit construction of bivariate polynomial interpolation in the square. Moreover, the associated Lebesgue constant has minimal order of growth O(log 2 (n)). Here we show four families of Padua points for interpolation at any even or odd de
