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, STELlations

_{10}(1) ... STELlations_{10}(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.**1. Stellations program. 2.
