1. 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.
