Truncated Icosahedron

Posted by Cecilia on Wednesday, March 19, 2003 · 4 Comments 

Meet the latest addition to my origami family. It’s a truncated icosahedron (12 pentagon faces, 20 hexagon faces, 90 edges, 60 vertices) i.e. a soccer ball. I made this one using Pentagon-Hexagon Zig-Zag (PHiZZ) units from this site. Achieving “proper 3-edge colouring” was definitely not easy. I was close several times and each time had to disassemble a chunk of the polyhedron and start again. If any of you C&O-types know a good algorithm for colouring polyhedron edges please let me know because right now I’m depending on brute force. The end result does make it all worthwhile though.

    It’s mine. It seems that picking up origami as a hobby meant picking up origami-still-life-photography as a hobby too.
