5. 92 Stellations with example of model of an Truncated icosidodecahedron.
- Roman Chijner
For different parameters t and q, by choosing different combinations of sliders (k4, k4', k6, k10), you can get different structures. In the applet, I selected 92 cases, among which there are many known structures with a different number of vertexes: V=12, 20, 30, 60, 120. Using the sliders (k4, k6, k10), it is possible to sort through all polygons with 4-, 6-, 10-vertices that have the following attribute: their planes are at the same distance from the corresponding faces of the origin polyhedron. For each type of polygon, vertices can be traversed in different ways. For example, 5-gon can be represented either as a convex pentagon or as a five-pointed star. In the applet for each type of polygon there are several ways to bypass their vertices. For example, STELlations10(1) ... STELlations10(4). The slider k4' goes over all the quadrilaterals (there are 1770 for a specific case) whose vertices are symmetrical with respect to the centroid of the origin polyhedron. Here they are divided into groups of quadrilaterals with the same areas for specific parameters t and q.
