The algorithm of geodesic breakdown involves the following steps. If the main polyhedron is an icosahedron, then it consists of twenty triangles. They are further projected onto the surrounding sphere. The vertices of this triangles form the main mesh. To obtain the resulting grid, you must perform a further breakdown of this triangles.

*Class I1; 3. Six triangles are connected by six edges.*
