Abstract

The paper analyzes the possibility of obtaining polyhedral shapes formed<br/>by combining polyhedral surfaces based on the segment surface of<br/>elongated concave pyramids of the second sort (CeP II-10, type A and type<br/>B). In previous research, CP II type A and CP II type B were elaborated in<br/>detail. In this paper we discuss further potential of these polyhedral<br/>surfaces, on the example of combining them with Archimedean solid -<br/>Truncated dodecahedron (U26). The faces of this solid consist of 12<br/>decagons and 20 triangles. On the decagonal faces, decagonal polygons of<br/>the CeP II segments ( CP II-10) can be added, which provides the new<br/>polyhedral composite forms that are, furthermore, concave deltahedra.<br/>There are considered possibilities of obtaining polyhedral shapes by<br/>combining sheet segments CP II-10-A, as well as of CP II-10-B with<br/>U26. Finally, a couple of new shape suggestions are given: compound<br/>polyhedra, obtained by intersection of paired composite concave<br/>polyhedra originated in the described manner
