The Color-Matched Dissection of the Rhombic Enneacontahedron

George W. Hart


This is The Color-Matched Dissection of the Rhombic Enneacontahedron .The plexiglass shell, shown empty below, opens up and is filled with 120 rhombohedral pieces in five different shapes.  The pieces are constructed of acid-free card stock, assembled with tape, colored with five colors, so that opposite faces are always the same color.  They fit together to fill the solid, matching color to color, resulting in a symmetric coloring of the 90 visible outside surfaces. This was the topic of my talk at the1997 Art and Math Conference, in Albany.
