Enneahedra with 14 vertices

Steven Dutch, Professor Emeritus, Natural and Applied Sciences, University of Wisconsin - Green Bay

There are 50 members of this class. All the groups are small, with at most three members, but quite a few require multiple views.

The first two members (444555555 and 333555666) have threefold symmetry, but the symmetry axes are located at vertices where three pentagons or hexagons meet. 334555566 has twofold symmetry relating the opposing hexagon faces.

444444477 is just a heptagonal prism. The symmetrical view is pretty superfluous.

334444488 is an octagonal wedge with opposing faces related by mirror symmetry.
