Abstract
Abstract A block system useful as a puzzle or game consisting of a group of solids adapted to be assembled into a larger regular polyhedron. The solids each have shapes that are determined by an assembly of components that include a tetrahedron and one or more fractional sections of an octahedron. The fractional sections comprises one-eighth and one-fourth sections of a regular octahedron.

Claim 5
Dependent Claim
76 words
A block system consisting of solids adapted to be assembled in selected relations to form a hexahedron having a line through its geometrical center, a plurality of said solids each having shapes determined by an assemblage of components including a tetrahedron and at least one fractional section of an octahedron, each said tetrahedron having an edge extending from a point on said center line of said hexahedron to an outer edge defining part of said hexahedron.
Claim 6
Dependent Claim

Claim 7
Dependent Claim
76 words
A block system as set forth in cLaim 4 wherein said plurality of solids consists of eight solids each including a tetrahedron, with pairs of tetrahedrons of said eight tetrahedrons having abutting edges extending from the center of said cube to the midpoint of an edge of said cube, four pairs comprising said eight tetrahedrons, each pair having abutting edges extending from the center of said cube to the midpoint of different edges of said cube.
Claim 8
Dependent Claim
51 words
A block system as set forth in claim 3 wherein said hexahedron is a cube and the point from which said edge of each said tetrahedron extends is the center point of an outer face of said cube, said edge extending to a corner defined by three edges of said cube.
Claim 9
Dependent Claim
