| 1. | This uniform polyhedron compound is a composition of 2 icosahedra.
|
| 2. | The truncated 600-cell consists of 600 icosahedra.
|
| 3. | The centers of the icosahedra are located at the fcc positions of the lattice.
|
| 4. | From the remaining 53 boron sites, 48 form icosahedra and 5 are bridging sites.
|
| 5. | Its facets are hemi-icosahedra.
|
| 6. | The truncated octahedral cells become icosahedra.
|
| 7. | Then the four side-facets of the prism, the triangular prisms become tridiminished icosahedra.
|
| 8. | They have elongated, geminate capsids with two incomplete T = 1 icosahedra joined at the missing vertex.
|
| 9. | The 1938 book on the fifty-nine icosahedra resulted, written by Coxeter and Patrick du Val.
|
| 10. | If the twinned icosahedra were independent without twinning then B23 would be a bridge site linking three icosahedra.
