The "'Pyraminx Crystal "'is a dodecahedral puzzle similar to the Rubik's Cube and the Megaminx.
22.
On the other hand, there are many other polytopes with hemi-dodecahedral facets and Schl�fli type { 5, 3, 5 }.
23.
But here again, its low hardness ( 2.5 4 ) and perfect dodecahedral cleavage preclude sphalerite's wide use in jewelry.
24.
The "'rhombic dodecahedral honeycomb "'is a space-filling tessellation ( or honeycomb ) in Euclidean 3-space.
25.
The two dodecahedral cells project onto the entire volume of this envelope, while the 12 decagonal prismic cells project onto its 12 pentagonal faces.
26.
Like the 11-cell, it is also universal, being the only polytope with hemi-dodecahedral facets and hemi-icosahedral vertex figures.
27.
Indirect lighting was demonstrated again, using a 128x128x128 voxel grid representing local light intensity, and voxel cone tracing along 12 directions ( dodecahedral ).
28.
It is self-dual and universal : it is the " only " polytope with hemi-icosahedral facets and hemi-dodecahedral vertex figures.
29.
Some regular crystals such as garnet and diamond are also said to exhibit " dodecahedral " habit, but this statement actually refers to the rhombic dodecahedron shape.
30.
The 4-D 120-cell software sequential move puzzle from Gravitation3d is therefore the 4-D analogue of the Megaminx dodecahedral 3-D puzzle.
