| Until the recent advances in computational power, simulating the protein coat of an entire icosahedral virus would have been futile. |
| We find that some atoms leave the decagonal layers to form icosahedral clusters. |
| However they are of a very high quality which is not so frequent in India and often have more complex morphologies, such as icosahedral and bipyramidal shaped beads. |
| They suggested that spherical viruses such as Tomato bushy stunt virus had icosahedral symmetry and were made from 60 identical subunits. |
| It is nonconvex with 60 golden rhombic faces with icosahedral symmetry. |
| But because of their fivefold symmetry, icosahedral clusters can't combine to form a regular crystal. |
