icosahedra's Usage Examples:

Boron suboxide (chemical formula B6O) is a solid compound with a structure built of eight icosahedra at the apexes of the rhombohedral unit cell.

Apart from RdRp, viruses in Duplornaviricota also share icosahedral capsids that contain 60 homo- or heterodimers of the capsid protein organized on.

icosahedra, octahedra (as triangular antiprisms), and tetrahedra (as sphenoids).

They have elongated, geminate capsids with two incomplete T1 icosahedra joined at the missing vertex.

capsid, which is round with isometric, icosahedral symmetry and has a triangulation number of 3.

It can be named by its Schläfli symbol as {5, 3n − 2} (dodecahedral) or {3n − 2, 5} (icosahedral).

its structure is highly complex, with a mixture of C-B-C chains and B12 icosahedra.

isolated B 12 icosahedra are not stable, due to the nonuniformity of the honeycomb; thus boron is not a molecular solid, but the icosahedra in it are connected.

by its Schläfli symbol as {5, 3n − 2} (dodecahedral) or {3n − 2, 5} (icosahedral).

In 1987, An-Pang Tsai and his group at Japan's Tohoku University made an important breakthrough with the synthesis of the first-ever stable icosahedral quasicrystal.

In fact, an icosahedral graph is 5-regular and planar, and thus does not have a vertex shared by at most four edges.

Symmetries once thought to be forbidden for solids are actually possible for quasicrystals, including solids with axes of five-fold symmetry and three-dimensional icosahedral symmetry.

The virus particles have a distinct shape; each virion has an icosahedral head that contains the viral genome, and is attached.
