Lau's Tetrakaidecahedron
Above:Solved
Click a thumbnail to see its larger version and description.
A 3x3x3 half-regularly truncated on all 8 corners. The result has a barrel like shape.

This puzzle is part of the series "Sharp Corners". All modifications of this series are made by truncating an 3x3x3 on its corners. These truncations are not regular as in the Half Truncated Cube. One dimension of the cut goes deeper than the other two. This half-regular style of truncating a corner was popularized by the Hexagonal Dipyramid. The cutting depths do have to go as deep as in the Hexagonal Dipyramid. The Triakis Tetrahedron is another example which uses half-regularly truncated corners too but with diffrent cutting depths.
The technical signature (28A00145000) indicates where to cut the original cube.
Some members of this series are made solely by truncating. Others receive additional extensions to "delete" some of the remaining faces.

The solid has no fixed name known but since it has 14 faces it should be tetradecahedron. The truncation could be viewed as a doubled Stumpfwürfel.
