Abstract
Disclosed is a geometric puzzle comprising a plurality of three-dimensional components of at least one type, each component of the same type being derived by notionally dividing a fundamental shape into a plurality of equal parts, said fundamental shape being selected from the group consisting of a regular tetrahedron having edges of equal length and a regular pyramid with a square base and also having edges of equal length, said components being capable of assembly into multiple composite shapes. Each component may be equal and identical to one another or each pair of components may comprise mirror images of one another. Surfaces of said components may be provided attractive magnetic elements to hold said components in a composite shape.

A geometric puzzle comprising:
- twelve “P” type components being derived by notionally dividing a regular pyramid with a square base and having edges of equal length into twelve equal parts, each “P” type component having two faces that are right-angled triangles and two faces that are isosceles triangles;
- and
- twelve “T” type components being derived by notionally dividing a regular tetrahedron having edges of equal length into twelve equal parts, each “T” type component having two faces that are right-angled triangles and two faces that are isosceles triangles;
- wherein:
- one face of each “P” type component is identical to one face of each “T” type component;
- each face of each component has magnets embedded therein to permit the components to be releasably mated to form composite shapes;
- each isosceles triangle face of both the “P” type components and the “T” type components have two magnets being placed on either side of and equidistant from a line of symmetry from the vertex of each isosceles triangle;
- each right-angled triangle face of each “P” type component has two magnets being placed on either side of and equidistant from a line 90 degrees from the midpoint of the hypotenuse of each right-angled triangle of each “P” type component;
- each right-angled triangle face of each “T” type component has two magnets being placed on one side of a line 90 degrees through the midpoint of the second longest side of each “T” type component toward the right angle of the triangle;
- and
- the poles of each magnet being chosen such that:
- identical faces of each “P” type component can releasably mate with one another;
- identical faces of each “T” type component can releasably mate with one another;
- the one face of the “P” type component that is identical to one face of a “T” type component can releasably mate with one another to form a space packer tetrahedron;
- and
- one isosceles triangle face of a first space packer tetrahedron and one isosceles triangle face of a second space packer tetrahedron can releasably mate to form a composite tetrahedron and another isosceles triangle face of the first space packer tetrahedron and another isosceles triangle face of the second space packer tetrahedron can releasably mate to form a mirror image of the composite tetrahedron;
- and
- wherein each of the twelve “P” type components and each of the twelve “T” type components can be assembled to form both a cube and a hexagon.
