A Group Of Polyhedra Arised As Variations Of Concave Bicupolae Of Second Sort

Abstract

The paper presents the variations of polyhedral forms based on the geometry of concave cupolae of II sort. There were considered only variations that include bicupolae of II sort, with bases connected directly or indirectly - using prism or concave antiprism of II sort elongations, and giroelongations by antiprisms. Considering that there are 14 (i.e. 7 x 2) concave cupolae of II sort, from n = 4 to n = 10, for each base we get 30 variations, making a total of 210 different solids.
