Secondly, the author of today's nicholicious puzzle is Anna Maria Hartkopf of the Citizen Art Project Polytopia, where you can adopt your very own polyhedron.

Thirdly, today's puzzle is joint work with the advent calendar Mathe im Advent (puzzles in German only) for students in grades 4-6 and 6-9, respectively.
