Note: It seems that this piece might have been written around the second world presented, which is the most elaborated and has a quite different - more earnest - tone than the others and the framing story. That piece can stand on its own and was in fact published in this way in German under the title 'Chronde'. Dated at its end to June of 1975. The title could be translated as The Repetition.

Synopsis: King Hippolypp asks Klapaucius and Trurl to construct a more perfect world than the one known. Successively they present four different ones, but each one turns out to be imperfect, too, despite the genius put into them. (names taken from a German translation)
