| 21. | The cantitruncation operation create new truncated tetrahedral cells at the vertices, and triangular prisms at the edges.
|
| 22. | As a result, the triangular prisms expand into hexagonal prisms, and the truncated tetrahedra expand into truncated octahedra.
|
| 23. | The dual graph of the Goldner Harary graph is represented geometrically by the truncation of the triangular prism.
|
| 24. | Their non-axial square faces, which correspond with the edges of a cube, are connected to the triangular prisms.
|
| 25. | There is a scissor construction ( I believe ) that reduces an individual chamber to a triangular prism.
|
| 26. | This cross-section divides the runcinated 5-cell into two tetrahedral hypercupolae consisting of 5 tetrahedra and 10 triangular prisms each.
|
| 27. | More than thirty forms of fruit-producing trees where in the garden : spiral, triangular prism, fan, cords, and candelabras.
|
| 28. | A radial nonsimplectic subgroup is ?!, which can be doubled into a triangular prism domain as ?!.
|
| 29. | It can be seen as parallel planes of square tiling with alternating offsets caused by layers of paired triangular prisms.
|
| 30. | As the name suggests, it can be constructed by elongating a tetrahedron by attaching a triangular prism to its base.
