Structural element, in particular placement game element, tile or inlay part,

• characterized in that the structural element has a circumference which connects the cornets of an equilateral, irregular pentagon (FIG. 1) with the angles 36°, 108°, 108°, 36°, 252° by the lines (b) or (c), or
• the corners of an equilateral decagon (FIG. 11b) with the angles 288°, 144°, 72°, 144°, 144°, 144°, 144°, 144° by the lines (a), (b) or (c), or
• the corners of an equilateral irregular hexagon (FIG. 11c) with the angles 72°, 72°, 216°, 72°, 72°, 216° by the lines (a), (b), or (c), or
• the corners of an equilateral irregular hexagon (FIG. 4) with the angles 36°, 144°, 108°, 108°, 72°, 252° by the lines (a), (b) or (c), or
