Concave pyramids of second sort (CP II) are formed similarly to concave cupolae of second
sort (CC II) with a comparable logic of emergence to the regular-faced convex pyramids …

In this paper, the geometry of concave cupolae has been the starting point for the generation
of composite polyhedral structures, usable as formative patterns for architectural purposes …

The paper presents the results of the study of the new set of polihedra, the Concave
pyramids of the fourth sort, the construction procedures for generating them and their …

As architectural structures, concave cupolae of the second sort (CC II) are suitable for
prefabrication, thanks to the uniformity of their elements—regular polygons. This paper …

U radu se analizira mogućnost dobijanja složenih poliedarskih oblika kombinovanjem
segmenata elongiranih konkavnih piramida druge vrste (CeP II-10, tip A i tip B). U …

Concave Cupolae of fourth sort (CC IV) are polyhedra which lateral surface is created by
folding a quadruple strip of equilateral triangles, while the bases are regular polygons. The …

The aim of this research is to examine and outline modularity of the selected representatives
of concave polyhedra of the second sort (C II), from the point of view of their high …

This study presents a continuation of the research on the concave polyhedra of the second
sort, adding to this family a new group of related polyhedra. They are formed over a specific …
