REGULAR AND SEMI-REGULAR POLYHEDRONS CONSTRUCTED FROM POLYHEDRAL COMPONENTS

摘要

A construction set, for building structures assembled from geometric parts having plane surfaces, comprises a plurality of geometric parts including at least one group of equal pyramids each having three, four, or five equal side faces and at least one part in the form of a semi-regular or regular polyhedron having at least one plane of symmetry. This latter part can be assembled from partial bodies, such as base-abutted pyramids, or may be a single unitary body. Adhesive means are provided to interconnect the geometrical parts selectively in either face-abutting or articulated edge-abutting relation.
