As far as I know, this is the only "snub truncated icosahedron" in
the
universe. Of course, there is no strong reason why anyone other
than
me would want to make one. But since I think it is quite
beautiful,
I thought you might like to see it also. It is hollow plaster ---
10 cm
in diameter --- and as fragile as an eggshell. To really
appreciate it, check out the high-resolution image available here.
The above computer-generated image shows its structure. It has
272 faces (20 hexagons, 12 pentagons, and 240 triangles). The
pentagons
and hexagons are regular, but the triangles are not quite
equilateral.
The word snub indicates the pattern with which triangles
separate
the faces of the truncated icosahedron (pentagons and hexagons
arranged
as a soccer ball).
