To play "hide and seek" with Wacław Sierpiński

 I have a few pages of manuscript in which I started solving Sierpinski's Problems. The base book, to which the pagination refers, is

200 zadań z elementarnej teorii liczb

     Countless editions have appeared, in countless languages. I have this in my electronic library.

 I also have a folder with Sierpinski's works somewhere. I will update them as I go.
