1. The title of this article refers to an interesting contribution by P. C. H. Mitchell ("Open and shut case for anions", Nature 1990, 348, 15-16; section : News and Views), which in turn refers to one of our earlier publications on a related host/guest chemistry (A. Müller, M. Penk, R. Rohlfing, E. Krickemeyer, J. Döring, Angew. Chem. 1990, 102, 927- 929; Angew. Chem. Int. Ed. Engl. 1990, 29, 926-927). In our opinion, the given title is now completely justified in the present work, because only closed hosts were described in our work at that time. The term "open and shut" can also be applied to the giant wheel-type clusters (A. Müller, S. Q. N. Shah, H. Bögge, M. Schmidtmann, Nature 1999, 397, 48-50).

9. The Pythagoreans believed that the world order, its harmony, and symmetry could be defined by numbers: Aristotle wrote in his famous book Metaphysics that according to the Pythagoreans - contrary to his own beliefs - the elements of numbers are the elements of all things and various types of structures could be differentiated by different numbers (see: A. Stückelberger, Einführung in die antiken Naturwissenschaften, Wiss. Buchgesellschaft, Darmstadt, 1988, p. 12).
