Abstract: The paving stone set consists of stones 11-16 each with six lateral boundary surfaces 1-6, 17-22. Four of these boundary surfaces 1 and 4; 3 and 5; 18 and 21; 19 and 22 are parallel to one of the other of the four surfaces, while the remaining two surfaces 2 and 6; 17 and 20 define planes which intersect at an acute angle.

The expansion joints are formed from two wedges directed opposite to one another, and therefore have an effect which is irregular in comparison with the support joints. The slotted boundary surfaces 2, 6 make it possible to lay the stones 11-13 according to the sloping angles selected in curves with small radii chosen as desired, whereby the wedge-shaped joints close gradually. The stones 14-16 serve as a supplementary curve set, and make possible the laying of Roman arrow patterns, as well as an Archimedean spiral.
